Bike Nine is an urban, unisex, 9-speed e-bike. The uniquely designed, asymmetric frame is compact, strong and light weight. Combined with its 20” wheels, it’s highly manoeuvrable and offers an agile yet no-sweat riding experience. The compact size and low weight make Bike Nine handy to carry with you on the train, by car or up or down a flight of stairs.

Bike Nine’s 9-speed gearing makes it easy to set the pedalling cadence that suits your riding style. This is especially an advantage if you prefer a mixed riding style where you interchangeably ride with and without motor assist.

The battery that powers the intelligent rear hub motor is a handy, bottle shaped Li-ion battery placed on the seat post. Presently it is the highest energy density battery on the market. The battery has an up to 60 km range, and the small size and low weight of the battery make it easy to bring a spare for longer trips.

The frame is made of high quality, cold-worked, mandrel-butted Chromoly steel tubes, chosen for strength and durability. Chromoly steel allows for thin wall tubing, resulting in a slim, lightweight frame that will last for years of riding.


Bike Nine is powered by an intelligent, small and silent 250W rear hub motor. It is a pedal assist motor which means that it kicks in when you pedal and stops when you stop pedalling. The maximum motor assisted speed is 25 km/hr to comply with EU regulation.

The motor has four power assist levels, which are controlled from a smartphone app that also displays info about your speed, battery level, watt consumption and more.

The battery that powers the motor is a handy, bottle shaped Li-ion battery - presently the highest energy density battery on the market. The battery is placed on the seat post securely fixed with a magnet and a strap which makes it easy to detach for recharging. The battery has an up to 60 km range depending on the chosen power assist level, terrain, wind, riding style and rider. The size and weight of the battery make it easy to bring a spare for longer trips.
