Hi chaps. Received the new external controller this morning. So... Where do I start? Is there a step by step guide I can follow that you can point me in the direction of? This is where the fun starts!

OK, I've just ordered the KT one that Wheeliepete recommended first. Paid the extra to get it over in the next 7 - 15 days. So... During my wait what can I do to prepare for surgery? What tools will I need? I currently have.. - soldering iron, electric - need some new solder, only have thick stuff and flux for CH copper pipes - host of connectors and heat shrink tubing of various sizes - volt meter - cyclone battery connector has arrived, which has some hefty gauge cable to it. Making me wonder what other cabling I need to get - do I need to remove the blown controller board or is it fine just sitting there? - can I assume the existing ORO grip accelerator will still work? Etc., etc.

But I'm not going to turn and run too easily and really appreciate and will most certainly accept your offer to help and advise how to 'hack' things to make it all work after my blunder. LOL... Just remember to try and explain and direct as if talking to your grandmother / wife / child. I'll pick it up, I'm just starting from hazy memories of A level physics from over 25 years ago. :-)

Yes, it was the brushless one I'd selected and checked that it has the 3 phase wires (see attached screen shots). What kind of amps should I be looking for, ideally? Also, I hadn't selected an LCD screen simply because I didn't think I'd need one. If it's advisable then here's one for £15 more. https://rover.ebay.com/rover/0/0/0?mpre=https://www.ebay.co.uk/ulk/itm/323396809738 However, found this 24v 500w 30A brushell controller on Aliexpress. Under £30 delivered. https://m.aliexpress.com/item/32610339800.html?pid=808_0000_0101&spm=a2g0n.search-amp.list.32610339800& I'm also not clear on the whole sensorless thing. So if it's all going to get too complicated for a newbie I'll might just count my losses and walk away before I end up spending hundreds of hours and pounds on something that will hardly get used. :-/

Thanks again. Found this one on eBay which is 24v and 350w. https://rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.co.uk%2Fulk%2Fitm%2F163157053715 Only £15 delivered and I could get it next week (ish). Do you mind giving it a once over to check its suitable. It would be appreciated. Then, once I get a feel for how much the wife is likely to actually use it and therefore worth spending more money of beefing it up, I can go for something bigger. Cheers

Really appreciate your help chaps. Quick question regarding the controller... The link is to one that says 250w. The motor I have is 500w. I assume I need one rated accordingly or will that one be OK? I did do a search for 500w controllers but there were so many I have no idea what would be appropriate. If you could suggest a 500w controller I'll get it ordered. I can then spend the time waiting for it to arrive to educate myself more on all this.

According to this thread they are for a thermistor temperature sensor. https://endless-sphere.com/forums/viewtopic.php?f=2&t=8621 The link above is useful but some of the narrative / terms are above my head. Hoping to find some idiots guide based on 'buy this, swap it here, jobs a good-un'. But I might be over my head.

Just a basic ORO throttle... http://eclipsebikes.com/product_info.php?products_id=53

OK then... Having properly opened it up I think I can already anticipate the verdict judging from the scortch mark on the board. Even so, I'll upload the pics for a positive affirmation of this diagnosis and welcome any suggestions on what to do next based on... 1. I'm a complete novice w.r.t all this and electronics 2. The motor was a bonus and not essential. If I can exploit it for minimal expense, great, if we're talking £100 or more to fix / replace then not worth it based on usage it'll get. Having said all that, I'm always up for learning new stuff and having a challenge / puzzle to fix. Welcome your thoughts.

Hi, defo brushless.... I'll take more useful picks in a bit later. It has three white thick wires to the copper coils and two thin yellow wires.

Ah... Bugger. Well I've already had it opened as far as I could to look inside at the controller, magnets and poles. To open further would require detaching wires. But seeing as it sounds like the controller is toast I guess that doesn't matter much. I assume there will be guides to building external controllers on here, but if you can recommend any by providing a link it would be appreciated. Thanks again.

Ah, it's entirely possible that I connected it wrong, it was late at night. So what options do I now have? Do I need to be thinking about a whole new controller or will it be an obvious component that I could replace? Checked combined voltage and its about 25v. Thanks again.

OK then... Had some success followed by a bug fail so need some help. First of all, I managed to test the motor and it worked fine. I remembered I had a 24v drill so crudely use the battery wired the connections and gave it a go. Bit of a punt but the motor and accelerator worked perfectly. I was chuffed to bits. So I thought right, I'll I vest in two 12v 10ah batteries from eBay. Didn't need to be super in any way, just provide reasonable performance. https://rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.co.uk%2Fulk%2Fitm%2F253195815797 Got them yesterday, put them together, made a simple jump, and thought 'sweet, ready to go' (see pic). Went out to the garage, hooked it up and smoke came out of the motor. Disconnected ASAP. Tried my drill battery again... Dead. I can only assume that in my ignorance I've not accounted for current and fried something. I believe this motor has an internal controller. I've had the motor off and can only open the innards so far. I can see two yellow wires, one of which has some slight charing, which appears to have occurred near one of the poles which also has some very minor charing. I won't be able to look at anything more without disconnecting the wires (2 yellow, 3 white). This is really outside my comfort zone. Any suggestions or links to posts / threads that can help me with idiots guide? I'm gutted to have knackered a perfectly good motor and just hope I can fix it easily enough. Thank you in advance for any help. Rich

Thanks for your advice. I'll certainly give them a call to see what they say. Had a look at the LifePO4 batteries... c£300 a pop... Ouch! Is that what we're talking about for such a battery or are there other options? A quick Google comes up with other options like... https://m.ebay.co.uk/itm/Electric-Bike-24v-15ah-LiFePO4-Batteries-6A-Charger-Scooters-Bicycle-Battery-BMS-/283091742701 Would something like that not be suitable then? T. I. A.

Hi all, I'm new to this eBike stuff by simple virtue that I bought a tricycle for the wife second hand which, to my surprise appears to have a Cyclone 24V 500W motor installed, but no battery. I've drawn the conclusion that it's a Cyclone motor having identified the ORO Grip accelerator appears to be just for Cyclone motors. Now I have no idea about this stuff but am quite excited about it having read various posts on this forum, but I need your help. So the steps that I envisage I need to take are as follows... 1) confirm that this is indeed a Cyclone motor and kit 2) source a suitable power supply. Now initially this needs to be relatively cheep as I have no idea if any of this works. It does however look in pretty good condition. I'm in the UK so not sure what I'm looking for, where best to source it and at the best price. I've gleaned thus far that there are a multitude of battery and charging options. 3) test the motor now that I have power 4) diagnose any issues and resolve 5) get out and make the most of having inadvertently bought a ready made eBike Tricycle :-) Really appreciate any help or advice anyone can offer. Thanks in advance, Rich
