Our verdict
The GSD S10 remains the benchmark compact longtail: two children or 100 kg on the rear rack, on a bike that is only 1.92 m long. The 10-speed derailleur is the main compromise for heavy daily use.
Pros
- Only 1.92 m long, stands upright on its tail for storage
- Rear rack rated for 100 kg, room for two children
- Strong 85 Nm Bosch Cargo Line motor and four-piston brakes
- Strong 85 Nm motor pulls full loads up steep hills
Cons
- Derailleur needs more maintenance than a hub gear
- Child seats, rails and bags cost extra
- 37 kg is heavy to lift up steps
- Derailleur drivetrain wears faster under cargo loads
Ideal for…
- Families with one or two children and limited parking space
- Couriers and tradespeople riding in the city
- Families carrying two or three kids
- Couriers and commercial deliveries
- Apartments with limited storage space
Not recommended if…
- Carrying three or more children
- Riders who want a maintenance-free hub gear

Expert overview

Written by the AllCargo editorial team from manufacturer specifications and owner feedback. We did not test-ride this bike. How we review →
Who it is for
The Tern GSD S10 is for families and couriers who need real carrying capacity but have no room for a long front-loader. At 1.92 m it is barely longer than a city bike, yet the rear rack takes 100 kg and the whole bike is rated for 210 kg including the rider. Two children fit behind the rider with the right seats or the Clubhouse rails.
Riding and everyday use
Small 20-inch wheels keep the load low, so the GSD feels planted even with two kids on board. The Bosch Cargo Line motor with 85 Nm pulls hard from a standstill, and Magura MT5 four-piston brakes stop the 37 kg bike with confidence. With the 500 Wh battery, plan on roughly 40 km per charge when loaded; a second battery is available for longer days.
Before you buy
The folding stem and the ability to stand the bike on its tail make it easy to store in a hallway or lift. The Shimano Deore derailleur works well but needs more care than a hub gear if you ride daily in all weathers. Budget for accessories: seats, rails and bags are sold separately.
Frequently asked questions
How many children can the Tern GSD S10 carry?
Two children on the rear rack with suitable child seats or the Clubhouse system. The rack is rated for 100 kg and the bike for 210 kg in total, including the rider.
Does the Tern GSD fit in a lift?
Often yes. At 1.92 m it is short for a cargo bike, and with the stem folded it can stand upright on its tail, which takes much less floor space in a lift or hallway.
What range does the GSD S10 get?
With the 500 Wh battery, expect around 40 km per charge with a load in mixed conditions. A second battery can be added for longer trips.
What range does the Tern GSD S10 have?
With its 500 Wh battery we estimate about 39 km per charge with an 80 kg rider and 40 kg of cargo on rolling terrain. Use the range calculator above for your own scenario.
How much does the Tern GSD S10 weigh and how much can it carry?
The bike weighs about 37.3 kg and has a maximum permitted total weight (rider, cargo and bike) of 210 kg.
How much does the Tern GSD S10 cost?
Prices start at €6,100. The final price depends on configuration, battery size and accessories.
