Our verdict

The first-generation HSD P9 is one of the lightest ways into cargo biking: 25.7 kg, 1.63 m long and room for one child. The 50 Nm motor and 400 Wh battery limit it on steep hills and with heavy loads.

Pros

  • Only 25.7 kg and 1.63 m long
  • Folding stem, fits in many car boots and lifts
  • Handles like a normal e-bike
  • Relatively light for a cargo bike at 25.7 kg
  • Compact 1,630 mm length fits lifts and hallways

Cons

  • 50 Nm motor struggles on steep hills when loaded
  • Room for one child only
  • 400 Wh battery limits longer trips
  • Modest 400 Wh battery limits range with heavy loads
  • Only 50 Nm of torque — struggles on steep hills when loaded
  • Derailleur drivetrain wears faster under cargo loads

Ideal for…

  • Commuting plus school runs with one child
  • Small flats and public transport combos
  • Families carrying two or three kids
  • Apartments with limited storage space

Not recommended if…

  • Two children or heavy loads
  • Very hilly routes
  • You need to carry more than one child
  • You regularly haul heavy commercial loads

Who it is for

The Tern HSD P9 is for riders who want one bike for commuting, shopping and the school run, without the bulk of a real cargo bike. At 1.63 m it is shorter than most city bikes, and with the stem folded it fits in many car boots and small lifts. One child rides on the rear rack with a suitable seat or Tern's Clubhouse rails.

Riding and everyday use

At 25.7 kg the HSD handles like a normal e-bike. The Bosch drive with 50 Nm is smooth and quiet but runs out of breath on steep climbs with a child on board. The 400 Wh battery is enough for daily city trips; Tern quotes up to 110 km in ideal conditions, with a load expect around a third of that.

Before you buy

The total weight limit is 170 kg, so check that rider, child and luggage stay under it. The 9-speed Shimano Alivio derailleur is simple to service. If you ride with heavier loads or in hilly areas, the newer HSD with a stronger motor is the better choice.
