Crystalyte

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:

Hey Everybody,

Although I just listed my GoHub kit for sale (see marketplace), I am also considering replacing my dead SLA pack with LifePo or even Nicad?

Can somebody recommend what size pack I would need?

I currently have a GoHub, which is a Crystalyte 408 500 Watt motor, running through a 20 AMP controller. I was running 48V worth of SLA.

Thanks for your help.

Hi,

I'm planning on putting together an ebike using Crystalyte components and would like to have a brake light. I will want to put together a switching regulator to provide 12V for the lights and a relay for the brake lights.

I don't have the components right now but it is my understanding that the levers have normally closed switches so I would want to wire the levers into the coil side of the relay and have the brake light wired to the normally closed position. Is the correct?

I've attached a schematic.

Thanks

Ok I am building a no peadal moped with a crystalyte cruiser. So I will be experimenting with batteries and would like to be able to upgrade when technoligy permits.
So who has a reliable controller that is varible on the voltage adjustments?

I know about electric Rider are they the best cheapest?
Also who has the cheapest reliable batteries for a phoenix cruiser?

Here's the problem I have a 24v/10AH lithium and a 48v/20AH battery I need enough battery to run a 7240 Crystalyte front hub motor . Should I get another 48 v 20 AH battery and put it in parrellel with the 24v and the 48v battery that are connected in series ? Or can I put a 24v 20 Ah battery in parrellel instead , my fear is that the smaller of the two choices of battery will not do the trick of running the electric motor.
