Please note! Ride more cautiously under humid and rainy
conditions because the stopping distance could be longer.
More information on disc brakes, the replacement
of brake pads and disc rotors and the wear of these
components, can be found in the dedicated manual of
the brake suppliers.
7.5 Belt drive and 12-speed gearbox
7.5.1 Powerful advantages
These X Speed models come with a very user-friendly and low
maintenance drive train. Instead of the traditional drive train
with chain and derailleur gear the X Alpha 45 and X Speed Pinion
are being equipped with a belt and a fully enclosed 12-speed
gearbox. This unique combination of belt gear, gearbox and
brushless BIACTRON rear wheel motor comes with 3 powerful
advantages:
1. Contrary to traditional drive trains, the X Speed drive train
combination is whisper-quiet, low maintenance and very clean.
Never dirty pants again.
2. All Klever E-bikes and speed pedelecs have their motor in the
rear wheel, at the end of the drive train. For this reason, the
electric motor support has no negative impact on the shifting
performance and the wear of the drive train. By contrast, in
E-bikes and speed pedelecs with a centre motor, which is a
motor around the bottom bracket, the joined forces and torque
of both c motor go through all components of the drive
train. Consequently, shifting gears goes less smoothly and the
wear of drive train components such as chain, chainwheel,
sprockets and derailleurs goes twice as rapidly.
3. Last but not least, with the rear wheel motor the drive train
has no efficiency loss. Motor power and motor torque go
instantly from the tyre to the road surface without any loss.
7.5.2 Belt
The belt drive (image 57 & 58) is whisper-quiet while pedalling. In
addition, the belt drive is very low maintenance because it does
not require any grease or lubrication at all. In fact, grease and
lubrication should be avoided! Occasionally cleaning the belt
with some water will suffice. Because the belt does not need
any grease it will not attract any dirt and debris from the street.
Section 7.7 Wheels & tyres, deals with the belt tension and how
to disengage the snubber (belt tensioner) in order to remove the
rear wheel.

Bicycle parts
Your local Klever dealer has the proper tools for the
tensioning of the belt and the checking of the belt wear.
Caution! Just like with a chain drive, keep your fingers
away from the belt drive. Once your fingers get
pinched while the chainwheel is turning, this may
lead to serious accidents. The upper part of the belt
is covered with a belt guard, which has the same
functionality like a chain guard. It protects your pants
and prevents them from getting stuck in between the
belt and the chain wheel.
Please note! If you do need to touch the belt, for instance
in order to remove the rear wheel, then first turn off the
BIACTRON-system and take the battery pack out of its
docking station.
Please note! The belt can only be disassembled or
assembled under the condition that it is without tension
and there is ample play in order to lift the belt without
any force from the tooth shaped profile of the sprocket or
the chain wheel.
Caution! Never try to lift the belt off the sprocket or
the chainwheel using a screwdriver or another tool as
a lever. This will damage the belt with the chance of
making it unserviceable. Also putting back the belt on
the sprocket or the chain wheel with a screw driver
or another tool will lead to the same type of damage.
Never do this!
7.5.3 12-Speed gearbox
The Pinion C1.12 gearbox (image 57 & 59) is fully enclosed and
runs with very low maintenance in a whisper-quiet oil bath. The
12 speeds are offering a gear range of no less than 600%. This is
more than any other derailleur gear can offer. With the X Speed
gear ratios and a pedalling cadence of 60 revolutions per minute,
you cycle as easy in the smallest gear with ECO motor support 8
km/h. uphill as with the biggest gear with MAX motor support 45
km/h. on a flat road. All intermediate gears from 1 (smallest) to 12
(biggest) are very well balanced with ascending steps of 17%.
With the twist shifter in the righthand grip you shift the gears
(image 58). You can shift multiple gears in one time. Even
without pedalling or when reverse pedalling. You can shift under
load. However, in case you take the load off the pedals you will
have a smoother shift. More specifically in the following cases:
