Installing the rear wheel
1
Guide the rear wheel axle into the dropouts and ensure that the brake disc (on models with disc
brakes) is inserted between the brake pads. Ensure that the torque reaction collar is aligned so that it
fits into the left dropout (no illustration). Make sure the axle is inserted all the way into the dropouts
2
Tighten the axle nuts to 40Nm (30lb-ft) (= VERY TIGHT!). This torque is essential for the correct func-
tion of the propulsion system. If you do not have a torque wrench, use a normal wrench, and then
have your dealer check the torque of the axle nuts as soon as possible. Use only the original axle nuts;
otherwise you run the risk of damaging the axle threads
3

4
Keep the motor cables clear of the brake disc (on models with disc brakes) and the motor casing
5
Re-install the cable of the rear wheel brake (rim brakes only), and correctly adjust the rear wheel brake
(no illustration)
6
Place the larger neoprene cover over the plug-in connections, and the smaller neoprene cover closer to
the disc/motor to prevent the cables from contacting any moving portions of the motor

Installing the rear wheel with 142mm axle
A D-Series motor with 142mm axle is supplied with 2
bolts in place of the standard axle nuts.
The specified torque is 20Nm (15lb-ft).
Maintenance and Care
We recommend to have the spoke tension of the rear wheel and the torque of all screws checked by a
qualified dealer after the first 200km (125 miles).
In order to ensure extended use of the propulsion system, all plug-in contacts of the system should be
checked every two to three months and cleaned with a soft and dry brush, if necessary. It must be ensured
that no dirt or humidity penetrates the battery docking station when the battery is removed. The BionX
motor does not require maintenance.

Optimizing the Range of the Battery
The following factors influence the range of your battery:
1.
Climbing
Riding up steep hills requires much more energy than riding on flat ground. More effort, proper cadence,
and/or a change to a more gradual route can greatly affect overall range.
2.
Level of assistance
Choose the level of assist required based on riding conditions, rather than just riding in one particular level
all the time. Remember that energy consumption more than doubles from level 2 assist to level 4. Limit
the use of the throttle as much as possible to reduce energy consumption.
3.
Battery state of charge
Make sure the battery is fully charged before every ride. This will provide the best possible range from the
battery each time.
4.
Weight and load capacity
A heavier bike (and rider) lowers the range of the battery. Every ounce counts! Limit your cargo, think
about getting an efficient type of bicycle for the system, even what type of gear you wear.
5.
Tire pressure
Tires with pressure that is low will have increased rolling resistance, and require more energy from the
battery. It is important to regularly check your tire pressure, the max. pressure is typically written on the
sidewall of any tire. Slick, skinny, high pressure tires offer the most efficiency for you and your battery.
6.
Acceleration and constant speed
It is important to ride efficiently; electric propulsion systems consume more energy when accelerating
from a stand still. Try to keep your speed constant and retain momentum, starts and stops greatly affect
your overall range.
7.
Outside influences/weather
You will notice some difference in range when it is very hot or cold outside, this influences how quickly
the battery will discharge. Headwinds can also greatly affect system performance. Expect more range on
days with moderate climate.
8.
Cadence and Shifting
Keeping your cadence high (between 80-90 rpm) is the most efficient pedaling range for most cyclists. A
high pedaling rate in combination with the lowest level of assist will offer the most range, the more slowly
you pedal and the more you rely on the electric assist, the less range you will get. Use your shifters to ride
efficiently, just as you would with any other bicycle!
CAUTION
It is essential that the axle bolts are tight-
ened to 20Nm (15lb-ft); this assures that the
propulsion system functions properly.
