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 42c tyre which allows for greater traction.
