Tongxin Information

[sopht]

Thanks Jeremy, I think I feel as though I could fit a kit OK, but how much of a leap is it to getting separate motor, controller etc, even assuming that the right parts are chosen? This would be to keep costs to a minimum.

Do you think I would be able to follow wiring diagrams etc with only common sense and minimum experience of soldering etc. Or is this an impossible question?

Many thanks again.

If you're prepared to give it a go, then I can't see why you couldn't just buy the individual parts and put them together. Controllers and motors are best bought as a pair, as that way you can be sure they are compatible and will most likely already have matching connectors.

Throttles are pretty much standard in terms of voltage and output, but often use differing types of connector, so you may need to do some decoding of wire colours to work out how to hook one up.

Batteries are straightforward, you can go for a ready made pack, either a specific cycle pack in a case, or something like a Ping LiFePO4 pack from eBay (which comes with a charger but needs putting into a bag or case). Alternatively you can make a pack from individual cells that you can customise to fit into whatever space on the bike you think might be best. The only essentials with these approaches is to use a fuse and isolating switch in the power feed.

Is there anything going on with the group buy? I live in California. I've had a difficult time having Tongxin answer emails. I'm going to try calling next.

Hi Cody,
I have had no response from Tongxin since I last emailed regarding group buying 10 days ago. Rather disappointing, but not unusual.

tongxin dealership

Hi All.

I to have had no response from Diana Lin,I think this is the standard answer from Tongxin or any of there dealers I dont think I would now want to buy any kits or any bike with Tongxin parts fitted as there is no parts or back-up alfter you have purchaced
Come to think about it you cant even buy a kit in the fist place so you will not have to worry about them parts(unless you have already wasted your
good money on one.)

This firm makes the people at Loughborough look like saints(but I must say I only ever had good service from them)

A very disappointed JOHN

Not just Tongxin and nanomotor.co.uk, I've heard from others finding it impossible to contact the Alien motor chap now. Kit's seem quite problematic in this respect, either not represented as with BionX, or the representation very poor.

Only Heinzmann seem to have consistently dependable and knowledgable representation.

So who is a reliable source to buy kits and parts from?

What about these guys from Poland selling crystalyte kits?
Main page - EKONAPEDY.COM

Anyone had any dealings?

It is a bit frustrating.
I tried three times (2 x email, 1 x phone) to enquire about Ezee kits from current UK distributor and got no response.
By contrast I made several email queries to ebike.ca and received very detailed and helpful information back very quickly.
It would be great to have a UK based ebike.ca set up with a range of kit options.

I am new to all of this but I am up for a kit (or 2) if a group purchase can be established. I contacted Diana yesterday before reading this forum and got a reply within minutes asking me to introduce myself (i.e. what's my business) with the usual - we don't supply personal purchases. I would have thought a positive response is more likely if whoever is leading on the group purchase when contacting Diana were to introduce themselves as a buyer for an organisation or club, when enquiring on minimum order quantity, price etc.

Having looked at the details on their website I am confident I can put that part of the build together. What are the options for brake switches and throttles and where can they be sourced? Is it possible to rig this with a simple push button switch for a throttle proving either half power or full power like the cytronex trek in this months AtoB?

Been patiently waiting for some news as to whether John has managed to get any of the Tongxin kits.
Has anyone any information about this or is the group buy idea still a possibility? If anyone was able to organise it.

 

[rosjen]

I want one of these kits, so count me in. Has the controller issue been sorted?

Spoke length

Anybody got any idea on the spoke length needed to fit the TongXin into a 700c rim? And if so, where the best places to get them are?

My local bike shop is happy to make up a wheel, just concerned that the correct spokes might be hard to source.

Also, while on the subject, presumably the TongXin controlled uses the standard type of hall effect throttle assembly and cutoff brake levers (is the standard push to make or push to break)?

As far as battery meter is concerned, guess I don't really need one but if I change my mind an Alien style meter could be hooked up I'm guessing?

Cheers, BM.

Obviously the exact length needed depends on your rim. I can tell you the approx length of mine when I get home. The chap who built mine into a wheel had no trouble getting them. I didn't ask where he got them from but I know SJS does a wide range of lengths which others have used for electric wheel builds.
My Tongxin-supplied throttles and brake cut-outs appeared identical in operation to those used by other manufacturers. The throttles have battery indicator lights built in.
