Our verdict

The GSD P10 delivers the core GSD formula at a lower price than the S10: 1.91 m long, a 100 kg rear rack, room for two children and Tern's claimed range of up to 102 km. It is a pricey, accessory-driven system, but one of the most practical family bikes you can park indoors.

Who it is for

The Tern GSD P10 is for families who want to carry two children or heavy shopping on a bike that is barely longer than a city bike. At 1.91 m long and 68 cm wide, it fits in hallways and many lifts, especially when stood upright on its tail. The rear rack is rated for 100 kg and the whole bike for 210 kg.

Riding and everyday use

The Bosch Cargo Line motor with 85 Nm starts confidently with two kids on the back, and the 20-inch wheels keep the load low. Tern quotes 40 to 102 km with the 500 Wh battery; with children on board, around 40 km is realistic. Magura MT5 four-piston brakes and a 50 mm suspension fork rated for 210 kg keep the ride safe and comfortable. The 10-speed derailleur gives a wide gear range.

Before you buy

Child seats, the Clubhouse rails, footrests and bags are sold separately and add up quickly. The derailleur needs more care than a hub gear if you ride daily in all weathers. If you want the easiest setup for two children, check Tern's family bundles.
