Crystalyte X5 Motor Kit : rear motor only available Version: X5303

$850aud plus $140aud freight = $990aud
(price above is for 36v-100volt 20amp controller, a higher amp controller 36v-100volt 35amp is an additional $130aud)

The model which I have available is the X5303 which has plenty of top speed and torque for most situations . I have tested the X5304 model but at 85volts the top speed was just under 50km/hr. The X5303 has a higher top speed ( on 48volt you can get around 50km/hr ). At higher voltages higher top speeds can be achieved, maximum at over 90volts is apparently around 90km/hr ( not tested myself yet at higher voltages). So I'll go with the X5303 model in future unless someone has a specific need for a higher torque/lower top speed version ( X5304)

The X5 is a big , heavy and powerful motor weighing 12kg and a diameter of 24cm. Here is the x5303 installed for testing in a mongoose mountain bike.

Picture below shows x5303 motor on right compared to a standard size 408 hub motor.


The controller can run on 36volts up to 100volts. The standard controller that comes with the kit has a  20amps maximum current draw. A higher amp controller which has a maximum amps of 35amps is also available. Because its a very fast motor using it on a standard bike is risky to say the least. Standard bikes are not build for high speeds and some extra heavy duty brakes are a necessity.

Because of the high speed and power it is definitley for off road use only  in Australia, my view is that this motor is generally overpowered for use in bicycles. I would recommend the 408 motor by crystalyte or dual speed motor ( 408/4012) as more suitable for use in bicylces than the X5. I think the x5 is really more suited to small electric vehicle projects.

Whats in the kit:

1. X5303 motor ( other versions of X5 can be ordered but not kept in stock ).
Latest model supplied which requires no dishing or rim for rim to be properly centred in bike frame.

Motor is laced into a 20" or 26" rim ( other rim sizes are also available)
Rim used is a quite wide dual wall aluminium rim. I'm using very thick 3.2cm diameter spokes on these motors so that spoke breakages
will not occur ( tyre and tube shown in picture below not included). Picture below left shows x5303 installed in a 26" rim.

2. controller :
a. Standard controller : can run on 36volts up to 100volts, maximum amps is 20amps.
 Maximum power output of motor using 20amp controller at 98volt is 1500watts
b.  Higher amp controller: can run on 36volts up to 100volts, maximum amps is 35amps.
Maximum power output of motor using 35amp controller at 98volts is 2700watts.
Note: voltages over 48volt can be dangerous!!

Controller has on/off switch on one side, on the other side has led to show that controller is switched on.
All plugs that connect controller/motor/throttle/brake handles simply plug into each other very simply.

3. throttle: thumb type or twist type ( thumb type can come with leds for 36v or 48v systems).
Thumb type can come with led lights for battery voltage or just plain type.

Twist type can be a full length throttle or a half lenght throttle



4. torque bars (2) (these goes on the axle to stop the axle spinning in the bike frame) and torque washers (  2 lots ).

6.  7 speed shimano cluster comes installed on the motor - shimano model MF TZ07

7. left and right brake handles with cut off switches

Batteries are not included with the kit.

INSTALLATION:
Installation is quite straight forward, there are a few things to note:
1. please check the spoke tension is ok before using
2. ensure that you use the torque arms supplied with the kit, these stop the axle turning in the frame. Two torque arms should be used (supplied with kit )
The torque arms will need to be adapted to fit your bike, they are made from 5mm thick steel,  for instructions and suggestions on how to install the torque arms
see this  link . 

Note: the newer version of the crystalyte motors have the tyre centred in the middle of bike, no dishing of wheels is necessary.

Independent torque graph (below)  I had made on  an x5304 motor running on 36volts (sorry haven't done any tests on higher voltages or on the x5303 maybe at some time in future will be able to do that as time permits ).
Results from Torque Testing Machine:


Graph above is for a 36volt battery source
max torque is just under 50Nm using the 20amp controller.
