Motorized Bicycle Kit Installation
Our motorized bicycle kit installation takes typically anywhere from 30 minutes to an hour and a half. In 2004 Popular Mechanics wrote a feature article about How To Install A Motor on a Bicycle, they were able to install the GEBE motorized bicycle kit in 30 minutes.

5. Fig. C – Attach front and lower mount straps to the engine bracket with the three bolts and washers (provided), Tighten bolts Securely!
7. Fig. E(a) – Lower mount strap is installed on the outside of the rear forks, resting on the axel for proper belt tension.
Fig. E(b) – Proper belt routing – run belt around gear on engine’s drive shaft, between gear and tension arm bearing. Install belt on drive ring – with tension lever in OFF position, hold belt on left side of drive ring as you guide belt into the belt track of drive ring.
Fig E(c) – Front mount strap attaches where rear brake or fender tab bolts on. Front strap is malleable – you can bend it to fit your bike, BUT do not bend strap on bolt holes OR crease too sharply, positioning engine so that belt does not rub against brakes. Tighten axle nuts And nuts on Front & Lower mount Securely!
10. Fig. G – Trigger throttle just clips onto the right handlebar, in front of the handle grips. You can position the trigger throttle for use with either finger or thumb, whichever is more comfortable for you.
|**CHECK BRAKES FOR PROPER ADJUSTMENT**|
We recommend dual brakes and that they be in good condition, replace pads if needed.
Fig. K(a) – Hold tool while you turn the nut on gear with 4n1 tool (second tool included with unit). Left to loosen – right to tighten. Tighten Securely!!
Fig K(b) Nut connecting lever to engine bracket is Only nut of entire unit that should Never be TIGHT! Arm should swing freely, easily flipping from On to Off positions.
Fig. M – (for GZ25N only) If gear has been over-tightened and is not possible to remove – remove safety cover, loosen engine lock bolt (located on top of clutch housing/snout and under the safety cover). Rocking engine back and forth, remove engine from mount – drive shaft extends out from engine mount bracket.
Avoid damage to drive shaft, put a small piece of cardboard between shaft and pliers, hold shaft with pliers, use a 3/8″ wrench or 4N1 key and turn gear (left to loosen, right to tighten), should be easy to remove. DO NOT over-tighten changed gear, next gear change can be done without having to remove the engine. Re-install engine on drive shaft, BE SURE to push engine back COMPLETELY ON DRIVE SHAFT! **Tighten engine lock bolt firmly.
