It's currently off-season, so we work by appointment only and are not on site.

E-bike repair at the 2ratai.lt workshop is all about mechanics: we repair the mechanical side of e-bikes. We rebuild hub motors, replace brake pads, chains and sprockets, and repair wheels, bearings, axles and forks. An e-bike usually weighs more than a regular one, so the brakes, drivetrain and wheels often wear faster, and faults often start with humming, knocking or weak braking.

We don’t do electrical or electronics repair. Before starting work, we inspect the bike, tell you what needs fixing and how much it will cost. For more general work, such as a simple tune-up of a regular bike, see the page bike repair in Kaunas.

How much does a motor rebuild cost? An e-bike motor rebuild costs from 35 € plus parts. We give you the exact amount after inspecting the motor, as it depends on which bearings or gears are needed.
Do I need to call before coming? In season (16 March to 14 October) we work Mon–Fri 11:00–18:00. From 15 October to 15 March we work by appointment only and are not on site – please call before coming.
Do you repair the battery or controller? No, we don’t do electrical or electronics repair. We can replace the battery with a new one or fit an additional battery, but we don’t assemble or repair batteries.
Is it worth repairing rather than buying a new one? Mechanical faults – worn bearings, brakes, chain – are usually worth repairing. It’s worth discussing the repair with a mechanic after the bike has been inspected.

E-bike repair by symptom

Below are the most common mechanical symptoms we see on e-bikes brought to us. We don’t do electrical or electronics repair.

01from 35 €

E-bike motor hums

WhyMost often the culprits are worn hub bearings or gear parts. Sometimes the hum has simpler causes: a pad rubbing against the rotor or a wheel that isn’t installed properly.

Check it yourselfLift the wheel and spin it by hand: see whether the pad touches the rotor and whether you feel any tight spots.

What we doWe remove the wheel with the motor, rebuild the hub, replace the bearings and worn parts, lubricate everything and fit it back.

02from 35 €

Motor knocks or clicks when pedalling

WhyParts inside the motor can wear out or teeth can break, causing knocking or slipping. Sometimes a loose axle nut is to blame.

Check it yourselfCheck that the axle nuts haven’t come loose. If the noise is only heard under load, don’t ride and take it to a workshop.

What we doWe rebuild the motor and replace faulty parts and bearings. Which parts are needed becomes clear once we inspect the motor in the workshop.

03from 8 €

E-bike brakes weakly

WhyA heavier bike needs more braking force, so the pads wear faster. Other causes: contaminated rotors, air bubbles in a hydraulic brake, or worn rotors.

Check it yourselfIf the brakes are weak, don’t ride and take the bike to a workshop. Don’t touch the rotors with your fingers and don’t lubricate them.

What we doWe replace the pads, clean or replace the rotors, bleed the hydraulic brake and adjust it. More on this on the brake repair page.

048 €

Chain skips, gears slip

WhyBecause of the higher load, the chain and sprockets usually wear faster. A worn chain skips on a new sprocket, and an old sprocket can’t hold a new chain properly.

Check it yourselfSee whether the chain is dry and dirty, and read our chain care guide.

What we doWe replace the chain and, if needed, the cassette, then adjust the gear shifting.

05from 8 €

Creaking bearings or handlebar

WhyCreaking is usually caused by dried-out or dirty bearings: in the wheels, the headset or the bottom bracket. The extra weight of an e-bike puts more load on the bearings.

Check it yourselfSqueeze the front brake and rock the bike forward and back. If the handlebar feels loose, the headset bearings have come loose. Don’t overtighten by force.

What we doWe take apart, clean, grease or replace the bearings and adjust them. If parts are worn, we suggest replacing them.

065–10 €

Flat tyre on a hub motor wheel

WhyOn an e-bike, a wheel with a hub motor is heavier, and removing and refitting it takes care, which is why many people bring it to the workshop.

Check it yourselfCheck the pressure against the range printed on the tyre sidewall. More in the tyre pressure guide.

What we doWe carefully remove the wheel, replace the inner tube or tyre, then refit and secure the wheel. In season, we do urgent tyre changes straight away, with no queue.

078–15 €

Wheel wobbles or spokes have come loose

WhyA heavy bike puts more load on the spokes, so the wheel can go out of true, a spoke can break or the rim can buckle.

Check it yourselfSpin the wheel and see whether the gap at the brake pads or frame keeps changing.

What we doWe true the wheel, replace spokes, rebuild the wheel or replace the rim. More on the wheel repair page.

08from 6 €

Gears don’t shift accurately

WhyStretched cables, a bent derailleur hanger or a worn chain. Sometimes the cause is a wheel that was fitted incorrectly after a repair.

Check it yourselfCheck that the cable housing isn’t pinched and isn’t damaged.

What we doWe adjust the derailleurs and replace cables, housings or the hanger. More on the gear adjustment page.

E-bike repair myths

Myth. If an e-bike stops running, the motor or battery is to blame. In reality. The problem is often mechanical: worn brakes, a worn chain, seized bearings or a wrongly fitted wheel. We can inspect the mechanics, but we do not carry out electrical or electronics repair.
Myth. An e-bike needs the same maintenance as an ordinary bike. In reality. Because of the extra weight and load, the brakes, chain and sprockets usually wear faster, so they are worth checking more often.
Myth. You can simply ignore a humming motor and keep riding. In reality. Humming often points to bearings or parts that are wearing out. Wear can increase the longer you ride, so it’s better to show the bike to a mechanic.

Motor overhaul: what it includes

E-bikes mostly use a hub motor built into the rear or front wheel. Over time its bearings and gear parts wear, which causes humming, knocking or jerky power delivery.

During an overhaul, we remove the wheel with the motor, inspect the inside of the hub, replace worn mechanical parts, grease them and refit everything. Which parts are needed becomes clear once we inspect the motor in the workshop.

If the motor hums only while riding, but the wheel spins freely and quietly, tell us when you hand over the bike. It helps us find the cause faster.

Why an e-bike needs more frequent maintenance

The greater weight of the bike and the motor’s pulling force put more strain on the mechanics than on an ordinary bike. Brake pads, the chain and sprockets usually wear faster, while the bearings and spokes take a heavier load.

So it’s worth checking the brakes and gears more often and replacing the chain in time, before it wears out the sprockets. More on this in the chain care guide and on the service page.

chain and sprocket wear
wheel bearings and spoke tension

What we don’t do

We don’t do electrical or electronics repair. We repair the mechanical side, and for the battery we can replace it with a new one or fit an additional battery.

If you have an electric scooter, we repair its mechanical parts too – see scooter repair in Kaunas.
