Combining 4.5kW of electrical output with as much mechanical input as the rider is capable of, the Bomber electric bike displays phenomenal acceleration and hill climbing ability in any terrain. Pedal power is transmitted via its unique 9 speed sequential gearbox, with stopping taken care of by progressive 8 pot hydraulic disc brakes. Heavy duty long travel suspension soaks up the hits and allows the rider to maintain high speed stability leaving the Bomber electric bike in a class of its own.

Frame
Constructed from aircraft certified CrMo alloys, the one piece monocoque frames large polar moment of inertia displays exceptional torsional rigidity under the most extreme loading conditions. The new and improved battery fastening system allows for battery changeovers in less than 90 seconds. Evenly matched is the light weight yet ultra stiff CrMo swingarm which incorporates built in torque arms and adjustable wheelbase.

Motor
Now producing up to 4.5kW, the direct drive brushless DC hub motor has just one moving part between the motor and the ground increasing control, reliability and efficiency with virtually no sound emission.

Transmission
Pedal power is transmitted via the 9 speed sequential gear box which provides more than enough gears for any terrain. Changing gears is as simple twisting your wrist and the concentric swingarm pivot eliminates the need for chain tensioners, deralieurs and unnecessary maintenance. This translates to a smooth, quiet and efficient ride from start to finish.

Front Suspension
Standard issue 7 conventional dual crown forks soak up bumps with ease and can be easily adjusted for varying terrain at the turn of a dial.
For more extreme riders, the forks can be upgraded to inverted 7.9 dual crown forks which have 2 way compression, rebound, air preload adjustment and nitro charged floating pistons giving one of the most plush and comfortable rides that you can imagine.

Rear Suspension
The single pivot rear coil over monoshock is custom valved to iron out the back breaking bumps at the rear. With a simple turn of the compression and rebound dials, it can be adjusted for casual every day riding or more aggressive off road environments.

Brakes
The Bomber electric bike comes standard with powerful 6 piston hydraulic brake callipers giving any rider precise feedback using only 1 or 2 fingers on the levers. After a long hard ride theres never any doubt of pulling up when you really need it.

For added confidence in more treacherous terrain the Bomber electric bike can be upgraded to 8 piston callipers and matching master cylinders which improve modulation and pad wear through individually varied piston diameters and their large braking surfaces. The increased surface area of the callipers help to dissipate the heat on long downhill runs providing loads of stopping power when the speed becomes too much.

Battery
The high rate lithium cells and custom built battery management system monitors every cell in the pack throughout the charge and discharge cycles, maintaining precise cell balance and a cycle life of up to 1000 discharge cycles. Charge time is just 2 hours and the bikes can be charged at any 110V or 240V household outlet.
