The Allston is a folding bike that combines standard 700c wheels with a Gates carbon belt drive and Shimano Alfine 11 internal gear hub. Grease-less and virtually maintenance free, it’s perfect for urban riding and can be stowed until your next ride.

Hydraulic disc brakes provide superb stopping power, a RackStand offers cargo carrying capacity, and extra wide 38mm tires make it comfortable on even the roughest roads.
