Overview
Overview
The Alight Disc features an easy on and off frame design, touchpoints to maximize comfort and is available in Alight Disc City models equipped with fenders, a rack and a kickstand making the ride on the bike path or the commute to work more enjoyable.
Key Performance Factors
- Versatility: Run errands easily with the Alight’s included fenders, rear rack, and kickstand (select models).
- Comfort: Staying comfortable on your rides around town is a non-negotiable, so the Alight has an easy on and off frame, and comes with shock-absorbing grips, a pressure-relieving saddle, and a suspension seatpost.
- Control: The Alight’s powerful disc brakes work in dry or wet conditions, and with the increased fork clearance, you can install up to a 40c tire which allows for greater traction.
