Synergy Kahuna Review

The Synergy Kahuna is an amazing fat tire electric bike that looks and rides almost more like a motorcycle or moped than a regular mountain bike.

Solid aluminum frame construction

The Kahuna is available in 3 colours: black, blue and white.

Front and rear suspension creates a very comfortable ride.

Powerful 750 Watt Bafang geared hub motor feels very zippy and capable.

Hydraulic front and back disc brakes require less hand effort and offer adjustable-reach levers. Both brake levers also have motor inhibitors for safer stopping

great kickstand placement (with adjustable length),

They key must be inserted and left in the frame in order to power the bike on. The lock is below the main tube, making it difficult to see and awkward to reach.

Handlebars fold down for easy transport and storage.
