Overview
About this bike
The GSD is designed to carry two kids, a week’s worth of groceries, or a load of cargo, but it’s only 180cm long—the same length as a standard ebike. With Tern’s best-in-class folding technology, it packs down small enough to fit in a VW Touran or an urban apartment. Plus, it adjusts to fit riders from 150 – 195cm—so mom, dad and the kids can all share it. - Bosch Performance Line motor - Bosch dual-battery system for a range of up to 150 miles - Magura MT5 4-piston hydraulic disc brakes - Custom 62mm Schwalbe Super Moto-X tires with puncture protection - Heavy-duty frame-integrated rack - Boost thru-axle hubs - Wide range of accessories, including the Cargo Hold Panniers - Andros stem for handlebar height and reach adjustments - Fits two Thule Yepp Maxi child seats, or one Thule Yepp Nexxt Maxi seat—no adapters needed
