The Ascent 27.5 is the in-between Ascent: 27.5" wheels on a Small frame for big kids and smaller adults. It brings a 100 mm suspension fork and a quiet hub-drive motor to riders who are ready for a proper mountain bike but need a frame that fits, and it is happy on rail trails, bike paths and mild off-road rides.

  • More bump control: a VelectriX suspension fork with 100 mm travel.
  • Light-touch hub-drive: the VelectriX RX1 rear hub motor (250 W, 36 V, 45 Nm) with a cadence sensor and 4 assist levels.
  • Up to 50 km per charge: from a 36 V, 378 Wh Reention Bee battery.
  • Grippy, stable tyres: Kenda Booster 27.5" x 2.2" on 36-hole double-wall rims.
  • Reliable control: Shimano gearing and Shimano MT200 hydraulic disc brakes.

Road legal, pedal-assist only

Its 250 W motor only assists while you pedal, there is no throttle, and assistance stops at 25 km/h. The Ascent 27.5 is built to EN15194 and is road legal in every Australian state and territory.

The Ascent 27.5 comes in Silver, size Small, for riders 160–175 cm. It weighs 22.2 kg including the battery and is rated for a 110 kg rider plus 25 kg of luggage on a rear rack (optional accessory).
