Bike Maintenance

Keep it Clean

Parts Replacement

Brake Pads

Clean your e-bike with water or mild 

detergent and a non-abrasive sponge. 

Never spray your bicycle with a high- 

pressure water source (e.g. hose).  

If you need to replace any bike parts (e.g. 

worn brake pads), visit your local bike 

shop or go to velotricbike.com. Use only 

genuine replacement parts. 

Check your brake pads for wear at least once 

a month.
Disc brakes:

Replace brake pads that are thinner than 1mm.

Do not spray directly onto bearing points or 

electrical parts. Do not use harsh chemicals 

or alcohol wipes to clean your bike.

If you use anything other than genuine 

replacement parts you will compromise 

the safety, performance, and/or warranty 

of your bike.

Disc brake rotors:

Check the thickness/wear of the rotor. 
The minimum thickness is often printed on 

the disc.

Bike Maintenance

Tires

Derailleurs

Check your tires regularly before you ride. 

We suggest checking around once a week 

if you ride daily, or every other time if you 

ride less often. A properly inflated tire is 

the first step to improving your bicycle’s 

performance.

Shift the gears through all the sprocket 

combinations to make sure the derailleurs 

operate smoothly and correctly, and 

ensure the chain does not come off.

The recommended pressure for Velotric 

tires is indicated on the side of the tire. 

Pay close attention to your tire gauge to 

get the tire pressure as close as possible 

to the recommended pressure. Do not go 

above the recommended pressure.
