holes on the board, when moving up the spring, the elasticity will be raised to make the gap
between brake and rim become bigger and vice versa.
●The best gap between brake and rim is 1.5mm.
●The best position of brake wire stand is that it not to touch the front mudguard.
(4): Rear Adjustment of expansion servo brake
See in reference illustration C and D
adjust for rear brake
●Loose nut and pull-rod nut of the adjusting screw, unscrew the adjusting screw, while
the brake to make sure its position is on the1/3—1/2 of total distance in order the rear brake
shoe cling to the centre of the brake to reach ideal braking effect, and then screw down nut
and the pull-rod nut.
(5): Wheel hub tightening Adjustment
When you tighten the wheel hub, the fasten torque should be as below:
●For rear wheel hub, the fasten torque can not be less than 40-45 N.M
●For front wheel hub, the fasten torque can not be less than 18-20 N.M
Attention: Front wheel hub axle collets nut can not be over-tightened , otherwise can
cause warping at the front wheel (not be smooth & round )
4): Adjustment of Chain
See in reference illustration E
The chain may become loose after long-time riding, when you find this problem, you can unscrew
the nut of rear hub axle; adjust the chain adjustor for tightening the chain. Pull the chain down
10-15mm to its best tension.
Hold the pedal and rotate on counter-clockwise, the chain should be in normal state: rotate
well, without abnormality, without noise.
5): Assembly of the Pedal
The screw thread direction of the Right Pedal is right-hand thread; its lock direction is shown
The screw thread direction of left Pedal is left-hand thread; its lock direction is shown as
Please carefully read the manual before riding your E-bike; please do not lend out to
persons who do not know the details.
1) Your Mini has been equipped with brake switch-off device, left and right brake levers are
installed with brake power switch. No matter which brake you use, left or right during
riding, the power will be cut off -Automatically for safety purposes.
2) When the battery output voltage is reached the bottom index, Mini electronic control system
will cut off the power automatically to protect the battery cycle lifetime. When the battery
reaches its bottom voltage, you can just ride your bike by the pedal. And the battery
should be recharged full for the next cycling time.
3) Please switch off your Mini e-power when e-bike not in use.
4) Please ensure your e-bike while parked is stable and the kickstand is locked as well.
5) During riding please do not turn on the right switch throttle grip to full throttle, it can cause a
large start e-current, that may damage your battery. If somebody often steadily starts your
e-bike like the above, it may limit the battery cycle lifetimes.
6) Your e-bike once fully charged- riding range are more or less are subjected to the following
facts like: road condition, loading weight or wind direction etc. We suggested that you try to
pedal more during your start of riding and climbing and against the wind to help increase
your range distance and the longer life of the battery & motor .
7) Always try pedaling during riding on muddy or rough road.
8) During your start on the ramp-way for climbing, please first ride by pedaling, then start the
power switch for the e-motor assist.
9) During cleaning of your Mini, wipe with moist cloth or wet cloth, never using water hose or
squirt gun for the cleaning work.
10) Prohibit putting oil on the front brake shoes.
11) Big seat post
and middle seat post
should be cleaned, maybe put a little
sewing-machine oil for lubrication if necessary.
6: Battery Charger User Guide:
(the charger indicator: red means is charging , green means battery is full.
1) Be sure to fully charge the battery before the first use .
2) The charge time for the first initial 3 uses should be 12 hours.
3) The Li-ion battery can be stored with full charge. If you are not riding far distance, it’s not
necessary to charge the batteries frequently.
