Power level and gear combination guidelines
For best results and the longest life of your chain and cassette follow these guidelines:
1.
ON EVEN OR ROLLING ROADS, Use power level 3 (60%) and pedal. Change gears at will to
manage speed. Avoid power levels 4 (80%) and 5 (100%) when using 9
th
or 10
th
gear. The force
of acceleration at high power levels on these small cassette sprockets leads to premature wear.
2.
ON STEEP HILLS (greater than 20% grade), stay in first or second gear and leave the power level
set to 5 (100%). Avoid changing gears. Changing gears under load may cause the chain to break
or the sprockets in the cassette to bend. If you plan to ride off-road and encounter steep
terrain, it is advisable to bring a spare chain and a master link chain tool. The chain tool can also
be used to straighten out bent sprockets.
3.
ON LOOSE GROUND LIKE DEEP SNOW OR SOFT SAND, use power levels 3-5 and low tire
pressures (as discussed above), always start in first or second gear before changing gears to get
a higher speed. As with steep hills, changing gears under load may cause the chain to break or
the sprockets in the cassette to bend.
Electric Juggernaut Operation Cautions
1.
DO NOT use FULL throttle for prolonged periods of time. This will result in excessive heat
buildup in the motor, throttle and batteries. Think about what would happen to your car if you
redlined for prolonged periods of time...
the engine won’t las
t long. Do not abuse your system,
and it will last you a long time!
2.
DO NOT operate in excessive heat (over 100 degrees Fahrenheit) for a prolonged period of time.
Doing so may result in excessive heat buildup and some components may shut down due to
thermal protection.
3.
If you notice a decrease in performance or abnormal operation, cease electrical operation
immediately. Failure to do so may result in damage to electrical components.
4.
DO NOT apply the brakes abruptly when going downhill as this may result in loss of control. Use
consistent, gradual braking.
5.
