F.A.Q.

Q: How fast will the recommended hub kit make my bike go ?
A: 17-19 MPH with a 26" wheel kit. This assumes a 160 lb rider, flat terrain and
no wind.

Q: How far will a full charge of the battery pack take an ebike ?
A: A fully charged 7Ah battery pack should take your bike approximately 20
miles, assuming the same conditions as above.

Q: How long does it take to charge battery pack?
A: 4-5 hours if your battery pack is low, only a few hours if its not fully
discharged.

Q: How many charge cycles will my battery pack last ?
A: This is very dependent on how well you maintain you batteries. If you charge
your battery pack immediately after each use, it should last approximately
300-500 charge cycles.
SLA batteries DO NOT like to be left in a discharged state and their cycle life will
be shortened.

Q: What is the useful life of a hub wheel kit.
A: The wheel motor has no internal moving parts to wear out, so you should
have years of use from this kit.
All components are of the highest quality to also last years of service under
normal conditions.

Q: Is there any drag when you pedal without the motor assistance ?
A: There is only a slight amount of drag due to the magnets in the motor. Under
normal riding conditions, you won't even notice it !

Installation requirements. (for most kits)
These kits fit most bikes. Before you order check the following;
The front fork must have 3.75" clearance at the dropouts. (where the
axle mounts.) there should also be 3" clearance 4" up the fork. These
numbers are not absolute (fork can be "stretched" a little) but must be
close. (see installation instructions)

Recommended! 1. Hub Motor Systems consist of a motor built into the actual bicycle wheel: the motor spins around the center bearing of the wheel itself. This is by far the most efficient system available, since there no gears or shafts to waste energy or wear out. Hub motors are also sealed, so they can handle the elements of rain, mud or sand, much better than friction drive or gear driven systems...

2. A Chain/Gear Driven System consists of a motor connected to planetary gears and a belt or chain that drives the rear wheel gear set. CURRIE systems fall under this catagory. This type of system has very good low-end accelleration (torque), and will reach good cruising speeds. But it shares the same relative drawback as the friction drive systems: you loose a good portion of your energy through the use of gears and belts. These systems also tend to create noise: a high pitched whining sound created by the planetary gear set and chain combination. Also, this kit must be installed on the rear wheel of your bike, connecting its adapter to each and every one of the 36 spokes - a very time consuming and sometimes difficult task.

3. A Friction Drive System usually consists of a motor with a splined shaft that rides upon the tire of your bicycle wheel causing it to spin and propel the bike. ZAP kits and bikes fall under this catagory. While this system is inexpensive, it is not very power efficient since you are loosing a good portion of your energy through friction on the bicycle tire. It is not capable of reaching high cruising speeds, and tends to wear out tires quickly...
