Kit includes: motor/controller/throttle/spokes/torque arms/torque washers/brake handles
 

Why is it cheaper than the crystalyte 408? This is a very common motor style in china and is used in the chinese domestic market. The factory that I buy these from has been producing this style of hub motor for many years, it has supplied some of the larger ebike companies in china eg Luyuan company. The quality of windings and bearings has been quite good.

I did a test ride of the GL-1 motor against the 408 crystalyte (with Tony Mathews of Surfers Paradise he was riding the 408 motor back in about 2006) , I was riding the GL1, we were quite evenly matched, throughout the ride. Tony was using a 20amp controller on the 408 and I was using an 18amp controller with the GL-1, we were both running a 48volt system. We did about a 30km ride that day from Surfers Paradise to Burleigh Heads and back.  The performance in terms of top speed and torque seemed quite similar for both motors ( both mounted in 26" mountain bikes rims)

( insert pic me and tony doing test ride)



GL-1 only available for rear wheel ( there is some risk on some bikes using hub motors in the front as fork damage or failure may occur in particular aluminium front forks are not suitable)
 

Pics below the insides of GL-1 motor with side plate removed.( windings are 3 phase and star type connection), the motors have three thick wires and 5 smaller wires that come out the axle, they connect to the controller, the thick wires take the high current, the thin wires are for the hall sensors.

I supply 3 speed clusters on the motors, I can put a cluster with more gears on if needed, but I find you dont need all the gears if you have a hub motor for power.

The controller used is the infineon chip 6 mosfet type controller. It has regenerative braking. Some parameters such as maximum amps and low voltage cut off can be adjusted via computer using a usb-ttl cable and the program ( see infineon controller page)
The motor can be run on 36volt or 48volts, top speed in a 26" rim on 36volt 18amp is around 30km/hr.

Spokes: spokes are normal steel type ( not stainless steel which break) they are quite a bit thicker than normal bike spokes ( 2.3mm diameter). The motor has 36 spoke holes which is the same number as a standard bike rim. I can supply the motor already laced into a rim but it will effect freight costs and some charge for the rim depending on which rim you would want. I supply spokes to suit your rim size.

Brake Handles: the brake handles have small switches in them which can either be used to cut off controller power when the brake is applied as a safety feature or can be used to activate regenerative braking.

The motor can be used in different rim sizes from 16" up to 26" ( also 700c), top speed and torque will vary depending on rim size used.

Torque Graph of GL1 shown below:



Unloaded rpm approx 330rpm, maximum stall torque 50Nm, maximum power out approx 640watts.
 

Below is the original graph which I've edited to give graph above ( note torque testing machines rarely continue to stall torque due to limitations on the machines
but the final portion of the graph can be easily extrapolated, the original graph below the test was stopped at 41.8Nm ).

Note: At least one of the torque arms supplied with the kit must be used and also the torque washers. Installation of torque arms will depend on
type of bike and design of bike frame. ( for more info on torque arms and torque washers see link ). If the frame is aluminium then both torque arms must be used.
