Why riders pick it
- Low drag: the brushless motor can be ridden above 15.5mph with almost no resistance from the motor.
- Throttle help: a thumb throttle gives a boost when pulling away or when you need a rest; riding on throttle alone cuts range by up to 30%, so pedaling when you can goes further.
- Lockout fork: the RockShox Judy has a remote lockout for smooth roads and climbs.
- Serviceable frame: tapered head tube, BB68 bottom bracket, internal routing and a replaceable hanger.
