2.4 Maintenance and adjustments

2.6.1 IMPORTANT! Do not attempt to open the casings of the battery, motor or controller. It
could be dangerous and all warranties will become void. If you experience a problem,
contact our service department or the retailer.
2.6.2 Wheel spokes should be checked after 300 miles of riding. Handlebar and saddle tubes
should never be raised beyond the maximum permissible, indicated by a safety line around
the tubes. The recommended torque (tightness) of crucial fixings is as follows:
Front axle nuts.
Back axle nuts.
Handlebar and stem clamp bolts.
Handlebar stem expander bolt.
Seat pillar clamp nut/bolt.
Seat clamp nuts.
Crank axle Allen bolts.
Gear shifter nuts.
Rear carrier nuts.
Mudguard bracket nuts.
Other general torque settings depend on the thread size. M4: 2.5-4.0N.m, M5: 4.0-6.0N.m,
M6: 6.0-7.5N.m.
2.6.3 Your bike has a rear derailleur that will automatically tension your chain. However, if the
chain becomes loose or frequently comes off the front chain-wheel, please seek advice from
the dealer.
2.6.4 Brake levers should lock the wheels when compressed half way between their open position
and touching the handle bars.
2.6.5 Warning: Handlebar hand grips or tube end plugs should be replaced if damaged, as bare
tube ends can cause injury.
2.6.6 Brake pads must be replaced if the pad material wears to less than 1mm.
IMPORTANT! braking distances increase on wet or icy roads.
2.6.7 Lubrication:
6.7.1. Lubricate all pivot points on the derailleur and chain with light oil or chain lube on a
regular basis.
6.7.2 Once a year, have the dealer re-grease the headset bearings, front wheel bearings
and pedal bearings.
