Anything out there like Cytronex ? Want to covert and On One Pompetamine

eddieo · May 18, 2011

To do such a nice bike justice you need a nice kit..Wisper DaaHub (coming soon!) would be a great fit. Or if you want something cheaper that dont look to bad (discreet bottle battery) this in link to other thread:

I have considered just the same combination - Pompetamine plus Cytronex would be very nice.

If you can wait, Cytronex aim to have a kit out in the next few months.

Otherwise, The Electric Wheel Company might be of interest.

Cytronex will do a one off conversion on any suitable bike - not the one you suggest as the system doesn't work with disc brakes as far as I am aware. No other hub motor offers the same experience as the tongxin motor but the Cytronex doesn't come cheap.

KristinS....What a wonderful looking bike....I tried looking through the spec to see what weight that bike is without power conversion?....all the Bafang motors plus Lithium batteries plus wiring etc will add at least 7 kg to the bike excepting the Tongxin/Cytronix system which is lighter but at the expense of range and cost.
Would it not be better to keep your Pompetamine as a fast conventional bike and buy a second electrical bike,which has been designed from the off to accept the PAS. There are a number of nice e-bikes weighing low 20kg for less than the price of expensive hub conversions.
We looked at the Shimano 11 speed Nexus hub but it is still low volume production cost at present and the jump from 8 to 11 speed was a significant cost hike-on an electric bike I felt that with 400 plus watts available(motor plus rider) 8 speeds is more than enough but on a conventional bike the closer gearing has many advantages.

... what I actually want is to have a very lightweight conversion on my commuter bike. I want to be able to ride like a normal bike when I want or when the battery is dead. Basically I want a Cytronex system ...
I have a On One Pompetamine like this one which I just love to bits - However, as cytronex don't do kits can anyone advise on a similar front wheel system ?

Going around in circles before you get something is a pain and you have my sympathy. However, going around in circles after you have something is going to feel so good! ... my gut feeling is to advise you to wait as your on the same wave length as Cytronex and I am expecting their kits to be something special. I am waiting for them but I already have a CX700 so my position is different to yours ... Lets pretend that your not going to wait... Can you provide some more details so that the forum members can help you?
Are your forks Steel , Ali or Carbon or something else?
Do you want a Tongxin? Will you consider other motors?
Do you want the controller to provide you with a throttle?
Do you want a bottle battery?
Whats your budget?
What milage do you want to cover?
Whats the route like?

Thanks

There are now Tongxin motors that support disk brakes. I guess there's a good possibility Cytronex might offer them as an option for their kit. It would be worth emailing Mark at Cytronex to ask.

Main supply of DaaHub due next month I think

You have a choice of wheels with wisper. I feel pretty confident that this system which offers so much choice (battery placement etc,,,) will become very popular indeed

You will need an adapter (any bike shop) to convert 160mm disk to Wisper 180mm disk. I need one of these as well for my new bike....

My understanding is that the the new kit will have disc brake option.

HarryB · May 18, 2011

I know tongxin do disc compatable motors but my only concern is how the disc brakes will work with the cut-out switches. The normal system relies heavily on these working. It is possible that Mark has tested some hydraulic levers with in-built switches but I wouldn't have thought the kit would have these (straight off that is) and they would come out on the ready made bikes.

Have you thought of another bike to convert without discs - I looked at a few that had the Alfine and cable brakes last time I investigated getting a kit.

Firstly - thanks to all for your help thus far

ok so it looks like I'm going to have a problem with the Cytronex kit on my Pomp (even when are available) as they don't handle discs. Hmm

@Kitchenman

Forks are cro-mo and so I have no fear about fitting a front wheel drive system of low power. After all Cytronex fit theirs to alu forks I believe. I won't consider a rear wheel as I love my Alfine hub dearly

Tongxin does seem to suit my requirments best. But yes I'll consider anything that is lightweight and low rolling resistance like this

Not quite sure what you mean about controller providing throttle. If you mean PAS vs throttle then I'm easy as I've tested both and get on with both. Its way down the priority list anyway

Bottle battery - yes. I already have a chunky rear end due to the hub so a battery on top of is not ideal. Front motor, rear alfine hub and mid mounted battery seems to make sense

Mileage - not far. Maximum of 1o miles between charges and usually less. I'm prepeared to pedal and not just cruise off the battery. I live on Sussex coast and the headwinds can be brutal quite regularly. I'm looking for help cutting through that on a rainy morning commute. Hills I can cope with (more or less) but battling into the strong wind just sucks it out of me. Hills I come across when I'm riding for fun over the South Downs and so are ok. The wind is always on the commmute which is pretty flat along the coast

My understanding is that Cytronex WILL be supporting disc brakes in their new kits. I didn't think you would want a throttle which is just as well as I'm pretty sure Cytronex will not be supporting one! but .. I may be wrong ... (I'm working on a list which is a checklist of questions to ask members who are thinking about getting a kit and the throttle one is on the list! ..) I've got another thread which has died a death related to this. The "list" is summary of what members have done or are doing relating to kits. There is nothing in the "list" that cannot be found in the threads so I'd be delighted to share it with you.

Glad you did. I missed these the first time round! ... Excellent stuff! ..

I cant wait to get this kit...I particularly like the choice of throttle. normal twist or discreet thumb throttle that has 3 levels of assist buttons and press twice and it locks on like cruise control. brakes cut power as per usual or a dab on button....The dapush motor has been very well regarded in the top of the range Wisper Alpino's so is a tried and tested unit...cant wait to get this fitted to my lightweight bike I bet it will fly!

HarryB · May 18, 2011

Eddieo - have you tried the 906 yet? Dapush feels bulletproof, looks great and reasonably powerful but it is a bit noisy and not as good as the tongxin in the freewheel department (still quite good). I am sure that the cytronex kit will come but it sounds like a total re-engineer so may not come soon (and if it was coming I am sure Mark would want to publicise that fact).

yes I tried one earlier this year, did not notice the noise to be honest, hill climbing was excellent. Wisper have already said on another thread that the Dapush motor in new kit has little or no freewheel resistance....

come on you know you have always wanted one H!
