A mobile bike repair van that fixes bikes at your home or office in Vilnius

The business works. Now make winter pay rent.

In short

High confidence. The verdict rests on actual revenue, costs, repeat customers, reviews, contract terms and service time, although personal living costs and full-year records remain unknown.

Why: Winter income is too low and too dependent on one person and one van.
Keep: You proved people pay
Do first: Pre-sell the winter packageDays 1-14

The judge's statement

You do not have an idea to validate.

You have a profitable job you created for yourself, with 140 repairs, 42 repeat customers, two recurring company contracts and €2,300 monthly take-home in season. The weak point is equally concrete: revenue falls to €900 for five months, while your income depends on one mechanic and one €6,000 used van. Storage, servicing and e-scooter repairs soften that fall but have not solved it. Do not spend your budget making the van prettier or the website cleverer. Sell denser work, charge properly for convenience and arrange backup before illness or a breakdown turns a good week into zero revenue. The verdict strengthens when winter revenue rises above your required personal draw without adding permanent overhead.

The Judge, after hearing all four jurors

Scorecard

Problem9/10

You remove the documented hassle of transporting a broken bike and bypass seasonal shop waits, with 140 completed repairs proving demand.

Market6/10

Vilnius supports a working solo service, but the available evidence does not establish a large market and winter demand clearly contracts.

Competition7/10

Established workshops are numerous, but the supplied research found no direct Vilnius mobile competitor and your convenience wedge is clear.

Business model8/10

You take home about €2,300 from €3,100 seasonal revenue, and the €450 half-day corporate visits have particularly strong economics.

Founder fit9/10

Five years as a mechanic, a self-built booking site, an owned van and full-time availability closely match the work required.

Execution risk7/10

Service delivery is proven, but seasonality, routing and dependence on one mechanic and one used van remain material risks.

What decides it

Biggest risk

Winter income is too low and too dependent on one person and one van.

Five months at about €900 gross can erase the lifestyle benefit if that does not cover your personal draw, while illness or a van failure can reduce revenue to zero and disrupt company commitments.

For this to work, all of this must be true

1Winter services and recurring contracts can produce enough net monthly income to cover your stated personal living requirement from November through March.
2At least 2 of 20 qualified Vilnius employers will accept a paid corporate trial or quarterly contract at economically attractive pricing.
3New residential customers will still book when the basic service rises from €35 to at least €45, or when a separate call-out fee is added.
4Geographic batching can reduce travel time without materially lowering booking conversion or customer satisfaction.
5A repair reserve and backup delivery partner can cover a van failure, illness or injury without breaking company commitments.

How the jury voted

Their votes are evidence, not the verdict. The judge weighs them below.

The Investor

Early-stage investor

7/10build

“A proven, highly profitable one-person trade business that meets your lifestyle goals, provided you expand your corporate B2B base to offset the winter slump.”

For your stated ambition of a lifestyle business replacing a full-time salary, this is already working. Your primary commercial hurdle is surviving the five-month off-season, which you can solve by tilting aggressively toward year-round corporate B2B contracts. Keep your overhead flat, optimize your driving zones, and this is a sustainable livelihood.

Concerns

majorSevere off-season revenue collapse threatens year-round livelihood
Revenue falls from €3,100/month to €900/month for five months (November through March), which will likely yield less than €650/month in take-home pay after winter fuel, certificate costs, and supplies.
Fix: Sell more year-round B2B maintenance contracts where billing continues across all four quarters, or pre-sell winter overhaul/storage packages during late summer.
minorRevenue is strictly capped by single-operator driving and repair hours
You charge €35 for a basic service and €70 for a full service while spending unpaid time driving across Vilnius between scattered appointments.
Fix: Raise residential prices to reflect the on-site convenience premium over shops like Dviračių arena (€50+), institute zone-based dispatch days to cluster bookings, and prioritize B2B fleet visits.

Strengths

Exceptional net margins with minimal overhead - Because you own the van outright and operate under an individual activity certificate, your fixed overhead is under €400/month, allowing you to pocket €2,300 net on €3,100 gross in season (a ~74% net margin).
Highly efficient B2B recurring revenue model - Your two corporate contracts yield €15/bike/quarter (€3,600/year for 60 bikes) while consuming only half a day per client every three months, eliminating the unpaid transit time that drags down residential visits.
Proven repeat demand and local validation - Generating 140 completed jobs, 42 repeats, and 63 Google reviews at 4.9 stars in your first operational season proves strong initial demand for convenience over brick-and-mortar wait times.

Assumptions to test

Vilnius office parks and employers will buy quarterly commuter-bike fleet maintenance year-round. - Pitch 20 HR or office managers at Vilnius tech/corporate campuses a pilot program over the next two weeks to see if you can close 2 more contracts.
Customers will pay a premium for on-demand convenience rather than matching brick-and-mortar pricing. - Raise your online booking price for basic service from €35 to €45 for new residential bookings and measure booking drop-off.

Confidence: high

The Customer

Your target customer, simulated

8/10build

“I love having someone fix my flat tyre or tune my gears in my office car park instead of hauling a broken bike across Vilnius.”

You are solving a real, recurring headache for commuters in Vilnius who hate dragging broken bikes to crowded repair shops. Your pricing is fair, your 4.9 rating shows you deliver quality work, and as long as you bridge the winter lull, this completely fits what I want as a customer.

Concerns

majorWinter weather drastically cuts my cycling and need for your service
You reported revenue falling from €3,100 to €900 between November and March. As a cyclist in Vilnius, freezing slush and snow keep my bike parked inside for four months.
Fix: Lean heavily into the winter storage and overhaul package, or push corporate year-round contracts that guarantee baseline retainer revenue.
minorLack of physical drop-off makes same-day emergency repairs tricky if your schedule is full
You are a solo operator in one van. If you are booked three days out or working at a corporate site, I cannot get an urgent commuter repair done on the spot.
Fix: Keep emergency buffer slots in your Wix booking calendar with a slight rush surcharge.

Strengths

Eliminates the logistical headache of getting an unrideable bike to a workshop - If my chain snapped or my brake seized, getting my bike across town to Dviračių arena or Velostreet without cramming it into a clean car boot is a massive pain; having you pull up to my home or office completely solves this.
Direct turnaround beats the 10-day peak season waitlist - In May or June, traditional shops quote 1 to 2 weeks just to touch the bike. Paying €35 to €70 to get it back on the road in under an hour while I am working is an easy decision.
The B2B quarterly maintenance plan is an easy perk for office managers to justify - At €15 per bike per quarter, an employer pays negligible money (€150/quarter for 10 bikes) to keep employee fleet or commuter bikes safe without organizing external transport.

Assumptions to test

Vilnius cyclists perceive an on-site mobile van as equally capable and trustworthy as a brick-and-mortar repair shop for complex fixes. - Review existing repair logs from your 140 jobs to see what percentage were basic adjustments versus complex repairs, and ask repeat clients if they ever withheld complex jobs.
Companies with bike racks or commuter perks will continue paying the quarterly fee during cold months when few staff cycle. - Check renewal rates and feedback from your two current corporate clients when their quarterly invoices arrive in January.

Confidence: high

The Operator

Serial founder

8/10build

“You have a functioning, profitable solo operation with low overhead that neatly matches your lifestyle ambition.”

You have validated product-market fit, acquired 140 customers, and built a profitable lifestyle trade with minimal debt. Your primary operational bottleneck is the 5-month winter slump; focus your business development entirely on locking down more corporate fleet retainers to stabilize off-season cash flow.

Concerns

majorFive-month seasonal revenue drought threatens personal living cash flow
You reported revenue dropping from €3,100 to about €900 per month between November and March, which leaves very thin margins after fuel and baseline costs.
Fix: Contract at least 4 to 6 more corporate accounts or pre-sell winter indoor storage packages with guaranteed overhaul service during peak season.
minorSolo capacity ceiling due to urban transit dead-time
Driving across Vilnius between one-off €35 residential repairs caps you at roughly 4-5 jobs per day before driving and admin consume the schedule.
Fix: Introduce minimum call-out thresholds, cluster bookings geographically by weekday, or push corporate fleet contracts that concentrate 10+ bikes in one parking lot.

Strengths

Flawless founder-operator fit - With five years of professional bike mechanic experience, zero workshop lease overhead, and an already owned vehicle, your execution risk on service delivery is practically zero.
Proven unit profitability and lean cost structure - Taking home approximately €2,300 net on €3,100 revenue in-season demonstrates genuine operational efficiency, aided by low fixed tax rates and minimal software/tool overhead.
High-margin corporate batching - Servicing 30 bikes at a corporate site in half a day eliminates travel dead-time between residential calls and guarantees predictable off-season recurring revenue (€900/quarter across your 2 clients).

Assumptions to test

Your €6,000 used van will remain reliable without requiring major capital expenditure during peak months. - Conduct a preventative mechanical audit on the vehicle before April and ringfence €1,000 from current seasonal profits into an emergency repair buffer.
Vilnius office parks and tech employers have sustained demand for quarterly commuter fleet maintenance. - Cold-pitch 20 HR or office managers at Vilnius business centers with a standard 1-page corporate flyer offering a trial bike checkup day.

Confidence: high

The Skeptic

Devil's advocate

8/10build

“A working lifestyle business already generating cash, whose primary structural risks are five brutal Baltic winter months and zero personal redundancy.”

For your stated goal of a sustainable lifestyle business, this is already working and financially viable. There is no structural fatal flaw, but you must actively secure more year-round B2B contracts to bridge the 5-month Baltic winter slump and protect against solo downtime.

Concerns

majorFive-month winter demand collapse
Vilnius cycling drops significantly in winter. You stated revenue drops from €3,100 to €900/month from November to March, which provides minimal living income after baseline vehicle, software, and living costs.
Fix: Scale corporate B2B contracts and pre-sold winter overhaul/storage packages during August-September to lock in guaranteed winter cash flow before the cold hits.
majorSingle-point-of-failure risk (van and physical mechanic)
You operate as a solo mechanic with one used €6,000 van. If the van breaks down or you suffer an injury, you have zero revenue but remain legally bound to quarterly company commitments.
Fix: Establish a contingency partnership with a friendly workshop or subcontractor to cover service SLA guarantees during breakdowns or sick leave.
minorLow barrier to entry for established retail shops
Market research shows traditional shops like Dviračių arena and Velostreet dominate Vilnius bike repair. If mobile repair gains mainstream share, an incumbent with multiple mechanics can deploy their own branded van.
Fix: Lock in local business parks and corporate clients with multi-year or annual agreements where retail shops have no established relationship.

Strengths

Proven unit economics and existing traction - You have already completed 140 repairs, generated 42 repeats, secured 63 five-star reviews, and net €2,300/month during peak season with minimal overhead.
Defensible corporate recurring revenue - The two corporate contracts (€900 total per quarter across 60 bikes) pay year-round and provide high hourly efficiency compared to residential travel.

Assumptions to test

€900/month in winter gross revenue provides sufficient cash flow to sustain your living costs until the spring rebound. - Review personal cash reserves and track net take-home pay strictly across the next complete off-season (November through March).
Corporate bike programs in Vilnius have enough density to add 3-5 more corporate contracts without creating scheduling bottlenecks. - Pitch 15 HR or facility managers in Vilnius business hubs (e.g., Konstitucijos pr.) offering quarterly fleet maintenance before next season.

Confidence: high

The judge's rulings

8 concerns ruled on

3 upheld3 downgraded2 overruled

upheld3

The off-season revenue collapse threatens a reliable year-round livelihood.
The Investor
Revenue falls from €3,100 to €900 for five months. Storage, e-scooters and year-round contracts mitigate the fall, but their current volume does not establish salary replacement across a full year.
Scattered residential calls create transit dead-time and constrain daily output.
The Operator
Every cross-city trip attached to a €35 service consumes capacity that cannot be sold. Corporate visits already demonstrate the better pattern by concentrating 30 bikes into a half-day.
The founder and van are single points of failure.
The Skeptic
If you are injured or the van fails, delivery stops and corporate commitments remain. This is not fatal for a solo trade, but it needs a named workshop or mechanic backup rather than optimism.

downgraded3

A solo operator is capped by driving time and low residential prices.
The Investor
The ceiling is real, but this is a lifestyle business rather than a venture-scale company. Price testing, geographic batching and more corporate work can improve income without hiring.
The used van could require disruptive capital expenditure.
The Operator
This is a meaningful continuity risk, not a reason to reject a profitable operation. A mechanical inspection, cash reserve and temporary replacement arrangement are affordable protections.
Established shops can copy mobile repair because entry barriers are low.
The Skeptic
They can copy the format, but no direct mobile competitor was found in the supplied Vilnius research. Your reviews, repeat customers and company relationships provide a head start, although not a durable technical moat.

overruled2

The lack of a physical drop-off location makes emergencies difficult when the van is fully booked.
The Customer
A workshop would add fixed cost and undermine the mobile model merely to handle overflow. Reserved rush slots or transparent next-available times are cheaper responses, and no evidence shows emergency availability is costing meaningful business.
Customers may not trust a van for complex repairs.
The Customer
Your 4.9 rating from 63 reviews, 42 repeat customers and five years of mechanic experience contradict a broad trust concern. You should still examine whether complex work is being lost, but trust is not an established weakness.

Your defenses

5 countermeasures weighed

1 falls short2 partly holds2 holds

falls short1

A van breakdown or illness stops all delivery
“You own the van and carry insurance.”
Ownership reduces financing cost, not operational dependency. No backup mechanic, workshop partner, replacement vehicle arrangement or financial reserve was described.

partly holds2

The five-month winter revenue decline
“You offer bike storage with a full service for €60, repair e-scooters year-round and retain company contracts across all four quarters.”
These measures already produce about €900 per month and prove winter revenue is possible. They still leave a €2,200 monthly gap from the €3,100 seasonal level, and you have not shown that €900 covers your living needs.
Residential travel time limits capacity
“You use online booking and a fixed-price service menu, while company visits batch 30 bikes at one location.”
The corporate model is excellent because each €450 quarterly visit takes half a day. Online booking reduces administration, but it does not prevent scattered €35 appointments from consuming paid repair time with unpaid driving.

holds2

High fixed overhead could make mobile service uneconomic
“You own the van outright, built the Wix site yourself and operate without workshop rent.”
Your stated recurring operating costs are only about €400 per month before taxes and parts, and your actual seasonal take-home is about €2,300. The lean structure is demonstrated, not hypothetical.
Customers may not trust a mobile mechanic
“You bring five years of mechanic experience, complete repairs on-site and collect public Google reviews.”
A 4.9 rating from 63 reviews, 140 completed repairs and 42 repeat customers are strong evidence that trust and service quality are not blocking adoption.

How big it can get

Total market: €1.2M-€2.4Mper year
Unsourced planning estimate: 20,000-40,000 annual paid bicycle service occasions in Vilnius multiplied by an assumed €60 average service ticket.
Reachable market: €300k-€900kper year
Unsourced estimate: 5,000-15,000 annual service occasions that fit mobile delivery, storage or employer-site batching, multiplied by an assumed €60 average ticket.
Realistic in 3 years: €45k-€65kper year
Estimated three-year solo capacity: about €3,500-€5,000 monthly residential and winter revenue plus €6,000-€10,000 annual corporate contract revenue, while retaining a one-person model.

How these numbers were worked out

Pricing: Test a €45 basic service and €75-€85 full service for new residential bookings, with parts extra. Dviračių arena starts preventive maintenance at €50, so €35 underprices a service that also travels to the customer. Keep the corporate offer at €15 per bike per quarter only where bike density and scope preserve the current half-day economics; quote a minimum site fee for smaller fleets.
Unit economics: Actual seasonal revenue is €3,100 per month and stated recurring costs are about €400 before taxes and parts, producing approximately €2,300 take-home after the founder's reported expenses. For a €45 basic service, an illustrative contribution is roughly €38-€42 before tax and owner labour, assuming €3-€7 of fuel, consumables and payment costs per clustered visit; scattered travel will reduce this. Customer acquisition cost is currently unknown. If a €45 first booking produces one repeat booking at the same contribution, illustrative gross LTV is about €76-€84 before tax and owner labour. The existing corporate contracts generate €450 per half-day each quarter, or €3,600 yearly across both clients, before visit-specific consumables and travel.
Path to first revenue: Revenue already exists. The fastest incremental euro is a paid corporate bike-check day sold to an office manager, or a prepaid winter storage and full-service package offered to your 140-job customer base.

Questions you'll be asked

The questions a sharp investor, partner or bank will ask - and what a strong answer looks like for you.

1
“What did you earn across a complete 12 months after every business cost and tax?”
What they're testing
Seasonal monthly snapshots can conceal whether the business actually replaces a salary.
A strong answer
Show monthly revenue, parts revenue and cost, fuel, maintenance, insurance, tax and owner draw for a full year. Based on the current monthly figures, the preliminary annual revenue estimate is about €26,200, but actual records must replace it.
2
“How many more corporate accounts can you win, and why will they pay in winter?”
What they're testing
The case for stable income rests heavily on expanding a channel currently represented by only two clients.
A strong answer
Produce a pipeline of 20 qualified employers, paid-trial conversion data and renewal evidence from the existing two clients. A strong answer includes at least two new paid trials or contracts and confirmation that current clients renew winter invoices.
3
“Why is the basic service only €35 when a workshop advertises preventive maintenance from €50?”
What they're testing
They are testing whether you understand the value of convenience and the opportunity cost of driving.
A strong answer
Report the result of a controlled €45 price test, including booking conversion, average travel time, contribution per job and complaints. Keep the higher price if contribution per available hour improves.
4
“What happens to customers and company contracts if you or the van are unavailable for two weeks?”
What they're testing
A profitable solo business can still be fragile enough to fail its best clients.
A strong answer
Name a mechanic or workshop with agreed overflow terms, show appropriate insurance, document customer communication procedures and maintain a €1,000-€2,000 initial reserve adjusted after a van inspection.
5
“At what point does another booking make your day worse rather than better?”
What they're testing
They want to know your capacity, routing discipline and maximum sustainable owner income.
A strong answer
Track repair time, drive time and contribution by booking for two weeks, then state a daily capacity and minimum contribution-per-hour threshold. Use zone days, minimum call-out pricing and corporate batching to reject or reprice work below that threshold.

What you got right

Not everything needs fixing. Keep these - they're why this is worth your time.

You proved people pay
You completed 140 repairs rather than relying on interview enthusiasm or a landing-page waiting list.
Repeat demand is visible
Forty-two repeat customers show that convenience and workmanship produce more than one-off trial purchases.
Trust has evidence
A 4.9 Google rating from 63 reviews gives future customers a credible reason to let a mobile mechanic work on their bikes.
Corporate economics are sharp
Each €450 quarterly client takes only half a day, giving you recurring revenue with far less travel waste than residential work.
