Crystalyte

Hey guys,

Getting ready to order the Roadrunner 4825 power system only kit for my first electric bicycle build. Any ideas for other kits and who is a good reseller? So far I have been looking at this kit on Electric Rider and Wild Nature Solutions.

Are there any particular power system only kits (I already have the batteries) of different models and manufacturers/resellers I should be looking at? Just looking for some information on where to start from the experienced.

Thanks

I got the new motor and the new controller from two different sources. The motor had trailer connector on the phase wires and the controller had Anderson connectors. I matched the phase wire colors and switched the motor to Andersons.

The controller I purchased was an instant start type.

When I plugged everything tother I found that the motor didn't want to start without some help and it shudders and jerks at low speeds and under load.

Before I had my battery I hooked the controller up to a small 48V AC/DC adapter to check some things. While this was connected I moved the throttle accidentally and the wheel tried to start. Could starting the motor with not enough power cause a problem?

Looking at the hall effect wires I found:

Looking at the hall effect connectors it looks like:

Motor Controller

Brown Red
Black Black
Green Brown
Yellow Yellow
Blue Blue

I cleaned the hall contacts with contact cleaner with no success.

I kept the:

Motor Controller

Brown Red
Black Black

the same and tried all six combinations of the other three wires. The wheel didn't spin when the wheel was off the ground and the throttle applied.

I then tested the voltages of the hall effect wires as they came off the controller. I assumed black was ground. I found:

Red - Black 4.3V
Brown - Black 5.0V
Blue - Black 4.8V
Yellow - Black 5.0V

I was under the impression that you should't hook the +5V and ground in the hall bundle to the wrong terminal, but, since two if the wires are +5V I'm not sure what to make of that.

Anyone have any advice?

Given the extra batteries needed, extra weight, and increase wind resistance, how much increase in top speed can be gained using a 72v. Crystalyte 5303 versus 48v. ? If everything else is the same: my weight, bike frame, tires, etc. )

Hello,

I currently ride crystalyte 408 hub motor with 48V 12Ah SLA battery pack. My controller is the one with regenerative breakings (don't know the model though). I can currently ride around 40km/h (~25mph) on freshly recharged batteries and around 32km/h (~20mph) with partially drained batteries. My wheels are 26''.

I need more speed :). I would like to be able to ride around 25mph constantly or even more if possible.

I was wondering if I can add another 12V battery to make the whole pack 60V ? Would that fry my controller or engine?

I've read about some controllers not being able to handle more than 55V. Can I solve this problem by exchanging my controller to 36-72V one ?

How much can I expect from 408? I don't need acceleration due to the fact that I usually ride on even roads.

I'm a big guy...350. I put a Brute kit on a Worksman bike last year and I love it but...

I want to ride this to work. It's 20 miles RT. I can charge the bike at work.
Currently I have 48V 12ah SLA (two 24v 12ah in series)

The first day I rode to work the batteries gave out about a mile from work. I was able to make it but it was a scare and I want to be sure I have the power available.
On the ride home I pedal more because I don't mind if I sweat. The ride home I pedaled a lot more and the battery indicator turned yellow but did not cut out.

I want enough battery power to make it one way (in the morning when I don't pedal very much) and welcome advice selecting different battery technology.

I got the kit from Electric Rider and they only recommend SLA batteries. They do have a company on their site that sells Nimh batteries but don't really recommend them, but, if you're going to use Nimh that's who they would use.

I've heard/read that LifePo4 batteries may not be able to supply high current for long periods. I've heard that Nimh are sensitive to discharge/charge cycles...

I don't want to change the motor to a higher voltage unless absolutely necessary.

Is the info I've been reading old info?
Should I get Nimh or LifePo4?
Do you think 48v 20ah would be sufficient using either battery type or would 30ah be best?

Sorry for all the questions...thanks for any advice!

Working on my ground design but need to purchase motor kit before beginning the welding of the frames rear section so I can set up the disc brakes.

Hi again

I Just thought this information might help others in the future, 'don't' fit this motor kit to the front forks of the Dahon Jetstream P8 the forks are aluminium with quick release drop outs, I had to change my plans and buy a Dahon Speed D7 folder for this kit it turns out that the Speed D 7 is one of the few remaining chromolly steel framed folders with chromolly steel forks, made by Dahon, most of their other bikes are fitted with Aluminium forks which are not Ideal for front wheel motors.

Hi everyone I am complete newbie to ebikes I am considering buying a Crystalyte folding bike motor kit for one of my new Dahon Jetstream P8's I was wondering if anyone on this forum has fitted this kit to a Dahon Jetstream P8 or any of the other small 20 inch wheeled Dahon folders, I would be grateful to here from anyone who has tried this motor kit, it looks like it would be easy enough to fit, I was wondering what its performance was like for someone like me I weigh 11 stone, and ride a lot unassisted, but I was wanting to set up one of my Jetstream P8's with electric assist because I have know totally given up the car, and cycle every where if I can, there are some journeys that have some hills which I have been avoiding and I want to keep one bike for those, and the other one for the exercise rides unassisted.

Many Thanks to all

HI!
I'm planning to upgrade my 900w heinzmann kit with a crystalyte X-5304R-DB, Phoenix Cruiser Motor with disc brake.
What do you think of using it with a X-CT7240D 72V 40A Phoenix Speed Controller?
That's 3000 Wh of power.

I've find it in http://www.electricrider.com/crystalyte/parts.htm

The only suitable battery I can find to give this amount of power are the kokam.

This 10 Ah 36v 2.2 kg pack looks a good solution. The bms is limiting 30 aH, but in fact the battery can handle 50 Ah peak discharge. With two packs in series I can get 74v at 30 Ah, 2200 W of power.

Is anybody running a crystalyte at 72v? Is it performing ok?
thanks!

Just received my Rear 5303 motor and I had all sorts of pain mounting this
beast to a 2008 Kona mountain bike with 7"/7" travel. Took me a week or so of
filing, tweaking, and deciding which configuration and which washer and spacer
combo to use. Brakes rubbed real bad at first which was almost unbearable. Had
to space out the rear disc with some flat steel washers to get it to line up
correctly. Battery is 48V 20Ah LifePO4 and 48V 40A controller.
Top speed so far is 58.5 KpH. Here is a pic:
