Frequently Asked Questions:
What Size Frame Do I Choose?
Small:5'3" and shorter.
XL:6'2" and taller
What is the significance of wattage (W)?
Wattage is significant to the overall power of the motor. The higher the wattage of an electric motor system the more fast and/or powerful it will become depending on the gearing of the motor.
System wattage is a factor of the battery voltage and how many amps a controller draws. For instance, our most popular system is the 1500w system. To determine the overally system wattage rating, we multiply the voltage of the battery (51.2v in this case) times the amps of the controller (30 amps) which gives you around 1500 watts of peak power.
We feel this is a much better indicator of performance than any other measurement since this is what you will ACTUALLY be getting out of your system. For instance, if a 900W "Striker" system (our most torque oriented hub motor) was increased to a 1500W system, a significant improvement will be seen in hill climbing ability and overall power and a slight increase in speed.
What kind of motor should I get?
Striker: The "Striker" motor is ideal for riders looking for torque (hill climbing ability) and off-road use. The motor will offter greater efficiency than the others. Can travel atspeeds up to 26 mph at 48 volts. This is the motor for those who put hill climbing ability as their first priority.
Thunderbolt: The "Thunderbolt" motor isideal for riders looking for a happy medium between speed and torque. Can travel atspeeds up to 33 mph at 48 volts. This is the right motor for you if you want something that can "do it all", both good hill climbing power and speed.
Black Lightning: The "Black Lightning" is the fastest motor that we offer. It can overcome medium hills and travel at speeds up to 40 mph at 48 volts. This motor is for those who demand the highest speed without the need to climb hills.
What is the difference between "GEARLESS" and GEARED" motors you sell?
At Hi Power Cycles, we want to offer you the best electric bike systems you can possibly buy. Due to popular demand, we offer both GEARLESS and GEARED motors. Here is a breakdown of the pros and cons of each:
Pros: Incredibly smooth power delivery, quiter than the "geared motor", more robust design if you want to go off road, less moving parts, greatest reliablity, price
Cons: Weight (8 pounds more than geared motor), larger diameter motor (aesthetics)
Bottom Line: This is the motor you want if you want the best reliability both on and off road. Most customers choose this motor option.
Pros: Huge weight savings (8 pounds), smaller diameter motor (aesthetics), build in freewheel (no drag), higher efficiency, better midrange power
Cons: More moving parts (gears/clutch) that will need to be replaced down the line, price (more expensive option)
Bottom line: This is the motor you want if you really care about weight savings and good midrange power!
How is range determined?
Range is determined in near perfect conditions (dry smooth riding surface, totally flat ground, no wind, and 170 pound rider) with a light ~18mph cruise.
What charger do I need?
While all chargers will get the job done a charger upgrade may be in order if charging time is of importance.
The charging time formula is reasonably simple: Divide the Amp Hour (AH) capacity of your battery by the Amp (A) rating of your charger.
For example using the included 2A charger, a 10AH battery can be charged in about 5 hours (10AH/2A = 5 hours).
An upgraded 4A charger could charge the same 10AH battery in 2.5 hours (10AH/4A=2.5 hours).
An upgraded 6A charger 1.7 hours (10AH/6A=1.7 hours).
What upgrades are available?
Ebike Diagnostic Computer: The Ebike Diagnostic Computer is a digital dashboard and battery monitor designed around the specific needs of electric bicycles. Once connected to the power bus, the Ebike Diagnostic Computer shows the following information:
Volts, Watts, Amps: The instantaneous electric power being drawn from the battery.
Efficiency: How efficient the system is at any give time
RPM: How fast the motor is spinning
Speed, Distance, Time: All of the basic features of a bicycle computer, including the average and maximum trip speeds, plus a total distance odometer.
Speed Settings: There are 3 speed settings on the computer that you can use to limit your speed
What is a Torque Arm and do I need one?
A torque arm helps prevent motor from spinning out the drop-out (where the motor sits in on your bike). A good idea for front motors. Notnecessary, however, for rear motors under 2000w. Anything over 2000w, it is recommeded you get a torque arm to prevent any damage to your system.
Lights:Handle mounted LED lights ranging from 700-1200 Lumens.
Which battery is right for me?
Battery preference is based on the user's desire for range and weight control. Essentially higher AH affords more range while adding weight. Higher voltage affords more speed.
Two main categories exist, Lithium Iron Phosphate (LiFePO4) and Lithium Polymer (LiPo) of which the lighter but offers fewer cycles. All range estimates below are a maximum range at ~20 MPH on flat ground.
LiFePO4 batteries (Lithium Iron Phosphate):
38V, 10AHmax 20 miles7.5 lbs
38V, 15AHmax 30 miles11.25 lbs
38V, 20AHmax 40 miles15 lbs
51V, 10AHmax 25 miles10 lbs
51V, 15AHmax 38 miles15 lbs
51V, 20AHmax 50 miles20 lbs
LiPo Batteries (Litihium Polymer):
52V, 10AHmax 25 miles6.5 lbs
52V, 20AHmax 50 miles13 lbs
78v, 10AHmax 35 miles, 10 lbs
78v, 20AHmax 70 miles, 20 lbs
