Maintenance FAQ
How often should I service my e-bike?
A good routine is a quick safety check before every ride (brakes, tires, bolts), a clean and chain lube every 100 to 200 miles, and a professional service every 6 to 12 months or around 1,000 to 2,000 miles. Riding in wet or off-road conditions shortens those intervals.
Can I wash an e-bike with a hose?
Yes, use a low-pressure hose, a bucket and a soft brush. Never use a pressure washer, because it forces water past seals into bearings, the motor and connectors. Remove the battery first if you can, and keep water away from the charging port.
