Cyclamatic???

Just seen this bike advertised with hardly any info, it’s a non-runner as it needs wiring sorting. It’s got a 36v battery. They’re wanting £160 for it. Is it worth it if motor can be seen running, or is it best to steer clear?

I'd test the battery and charger with a multimeter

 

And ask how it failed and symptoms

 

without doing that id not pay 160

 

If battery is a goner then I'd only pay 80 quid for it. And only cos I have a mediocre spec 36v battery surplus (and several controllers) so I could repair for zilch plus time and sell on

 

But then I'm tight:)

Agree above with Kirstin check the battery voltage at least you will know if it's balanced and takes a charge. That alone doesn't mean the battery isn't knackered and voltage won't crash at the first sign of any load. If the hub turns /works then worth a punt if battery checks out, the issue being not being able to test ride it to see if the battery voltage crashes.

If the wiring is a mess or kaput for about £50-80 you can fit a new lcd and controller etc.

 

Barter for it offer £125 the hub will get 30 - 60 quid on ebay other wise the bike looks to be in good nick from the pic.

Seems to me that 'needs wiring sorting' is a euphemism for completely broken and I don't know what's wrong but a dealer told me that it would cost £400 to sort it out.

Apparently it's an 'unfinished project' which I always take to mean un-fixable. But the guy has fitted new sest, mudguards, crank, pedals etc. so he must have thought it was worth investing money on it. I don't mind getting my hands dirty but don't want a money pit. Might go and have a look and get more info.

Wiring is easy if its been butchered messed with replace easily enough with a new Kt controller , pas, throttle & speed sensor and with LCD is about £75ish off Aliexpress or PSWPower. All depends if motor and battery are working. Or you can get the cheaper one controller kit d8veh has been using from Aliexpress for about £55/£60.

So what was it like before it needed a new seat, mudguards, cranks and pedals.

Also, look how the rack is fixed, how do you get the battery out if you want to charge it inside a house?

OK, been to have a look, and it seems genuine. The story goes that this guy has bought it to 'do up', hence putting new bits on. The frame and everything looks in really good nick. He decided to upgrade to a 36v battery as it's a 250w motor and a friend was selling a 36v battery. Once everything was fitted the bike no longer worked. He has removed the old controller and tried a new controller from HK, but that also wouldn't work. He assures me the motor runs, and was willing to show me it running but I didn't have time to wait to see. He's got another controller, but didn't know what all the wires were for. He's isolated the 3 phase wires, the battery wires and the 3 hall sensor wires. While he's been trying to sort this, he's had chance of another bike, which he's bought and has lost interest in the old one. The battery fitted shows 41v. The bike comes with both 24v and 36v batteries, both chargers, and a couple of controllers that may or may not work.

Anyway, have decided to sleep on it, so any thoughts or advice would be appreciated.

I don't think that wll climb the hills round Tow Law.

Good point, never really thought of that. If it was definitely easily fixable I would take a punt and sell it on. But it's never going to be worth a fortune.

I wou;d take a punt at £160. I got mine up to over 30 mph and it would climb steep hills without pedalling. The motors are quite strong, so can give a lot more power than standard. I would guess that it just needs wiring up correctly. A new battery would be about £200 for a reasonable one - if it needed one.

What kind of controller would I need to buy if I couldn't get the one supplied to work?

All things considered id push for 120 and settle somwhere inmiddle

The guy has said he won't budge from price, it owes him well over 250

160 isn't unreasonable, and you should be able. to get a decent working bike for little further outlay

 

But it is a punt

Just about any controller will work with it. The one you tried probably will work if you wire it up correctly. Did you check that the separate ignition wire was powered?

I think the ignition wire was the problem, I haven’t bought it yet, still sitting on the fence. The controller is shown below

It says 48/60/64v, is this too big a controller for this setup. Here’s a pic of the wires if it’s any use.

That's a 48v controller. It won't work at 36v.

Well that’s probably why he can’t get it to work. Where’s the best place to get a decently priced controller delivered quickly please?

The Cyclamatic has a very rudimentary control system, which was fine in its day, but modern ones are so much better. If it were my bike, I'd spend the extra money and take the time to get it sorted with a sine wave controller and LCD, which costs about £60 to £70 from China. You can get a cheap controller from EBay for about £20, but you only get one power level, which is maximum, or worse still can be proportional to cadence. You won't know until you get it. Make sure you get one with a PAS connector.

 

The PAS works in the opposite direction on a Cyclamatic, so you'll most likely need to take the crank off and flip the magnet disc.

 

Finally, the controller compartment is very small, so most controllers don't fit, which means that you'll need to do a lot of wiring to mount the controller.

 

The S06S from BMSBattery and an appropriate LCD is what I'd use, as it's small enough to fit and gives the best function.

Cheers d8veh, as always, a fountain of knowledge. I think I'll just give it a miss. I'll stick with original plan of converting my old bike. Unless he decides to drop the cost, but I doubt he will.

The owner is only a 36v controller away from success.

 

If you wanted to be really really nice you could tell him, polish your halo and wait for karma to deliver your perfect ebike for buttons

Just a quick question, still thinking of buying this, was thinking of just fitting a cheap basic controller to get me away, then upgrade to a better one later. Could I fit a 24v controller and run it on both the 24v and 36v battery until I know if both of the batteries are OK?

I’ve just fixed one of my older BH Neo’s up, which means I’ll be flogging 1 1/2 upgraded Cyclamatics next week. In Derby.

 

I think there’s 3 batteries between them, 1 fully working bike and 1 with a bent crank. I just want rid really - it took almost a year for me to find the time to fix my Neo.
