Crystalyte

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'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.

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 hav

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.

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
