Update! I have just ordered a new 36/48 volt selectable Speed controller with programmable LCD display so will report on this upgrade when installed and tested and will post the link.

As I have just mentioned that is a potential downside of using a 24v Speed controller!

Hi, the only thing to note is on my particular system I can’t see where the speed limiter is so I may well change the ESC and also I have to check the battery level on the battery as the controller is set up for a 24v battery and if left to the cut out it will potentially damage the battery and take it below minimum voltage!

Hello and Seasons greetings to all. Just thought I would add something as could be of interest to anyone with a Halfords Connect ebike! Back in the summer I purchased a Connect ebike from a friend who had bought it at an auction and never got round to getting it up and working. The bike was in reasonable condition but in need of brake cables, rear brake shoes, tyres and most importantly a 24v battery! Firstly I tested the electrics and all was fine then renewed all the above except the battery. After lots of research on the net I decided to try a 36v 4ah li ion battery (24v stock!) Seeing as I had a cordless lawn mower battery that I had been using on a previous project, I had read that some of the Chinese speed controllers could handle extra voltage so I bit the bullet and tried it! UREEKA it works!! as I mention the battery is from lawn mower so I designed and 3D printed a mount that now bolts to where there are water bottle mounts are on the top of the frame. So all I can say is that this conversion has now been working for several months without any problems or overheating of motor or ESC , I have added a thumb throttle as well but to be honest I use it on peddle assist lowest setting as in medium and high settings has it pulling like a train and hits the speed limiter easily! so firstly if anyone’s thinking about trying this it’s up to you and your decision!! So if it all goes up in smoke don’t blame me but all I will say it has worked for me faultlessly and the bike is in use most days incidentally I have a hybrid diamond frame bike with a Cyclotricty front 250w conversion and a KMX Kobra trike with a Bafang bbs01 conversion but the Connect is now my every go to workhorse so guess that tells you what I think of it Happy Ebiking

Hi to all, just thought I would add to the discussion that I have fitted a Bafang BBS01 250watt to my new KMX Kobra and after having to extend all the switch, brake, controller and sensor wires plus design and 3D print mounts and brackets all is done and it is simply fantastic Highly recommended conversion.

Hi, I recently fitted a DIY 250 watt front hub kit supplied by Cyclotricity and apart from having to install some slightly thicker washers to shim it out in the front forks of my Trek 720 hybrid (700c wheels) all went well and I have been very pleased with it. Also a thing to note is the basic kit comes with Front hub/wheel (no tyre!) thumb throttle, sensor Brake levers, ESC, all good quality harnesses ( no instructions!) and mounting box and no led or LCD display and no peddle assist sensors! Also excellent next day Free delivery!! After an email to them with regard to the legalities to which they informed me it should be fitted with peddle assist to confirm with the UK EU regulations! Thought this was a bit misleading as not clear when ordering and this was only an option to add to your basic kit. However as an ex motorcyclist I prefer a throttle and have left it at that. Also incidentally I am running mine successfully on Bosch 36v 4ah power tool battery packs on my own designed 3d printer HotShoe bottle mount with great sucess. Hope this helps. JJB

Hi there, thanks for your reply to my post, I did previously read the link you sent me after doing my conversion and was relieved to see they said to put the Bosch batteries on your short list! I have been a keen RC modeler for many years and have been using Lipo batteries ever since they became available for use in Fixed wing and large scale Helicopters too. I did consider using my 6s 5000mah packs that I have several of, but maybe for my next project! Thanks again for your response. JJB

Hi, I'm new to this community but feel that seeing as I have been researching the whole Pedelec subject for a while now, and reading many post here, I feel its only right to share my experience for what its worth! I posted a piece earlier today on my introduction to ebikes on the subject thread of kits and mentioned that I am using a fairly low capacity Bosch power tool 36volt 4ah li ion battery to power my Cyclotricity 250W front geared 700c hub kit. I know there has been some mention of using alternative batteries on this site but haven't really heard of any recorded results. After CAD designing a Hot Shoe type mount that I have 3d printed and mounted on the down tube in place of the water bottle carrier I have had great results and intend buying more of these top quality cell packs . Firstly my reason for doing this was that when purchasing the kit I couldn't buy a battery from Cyclotricty as they where totally out of stock, I then couldn't decided on what bottle battery to buy online and got totally confused with all the ones on offer, and fears of cheap li ion cell quality in low end battery packs got totally put off so I figured for the cost of a power tool pack of a know quality (and good manufactures Guarantee!) it was worth a try My only possible modification is to add a Volt/Watt meter display to keep an eye on the pack as there are only three capacity indicator LEDs on the battery itself. If anyone has a similar experience I would like to hear . JJB

Hi and a happy New year to everyone here, I am new to this forum and have only recently come back to cycling after a mere 20 years. I very recently got the Pedelec bug after meeting up with an old work college that in his retirement had converted his bike with a Cyclotricty basic 250w 36v Geared front hub kit, and as a motorcyclist also added another manufacturers twist grip throttle and a generic 10ah bottle battery to complete his build. So after failing to refuse a ride out on his trusty steed I threw a leg over his standard Gents non suspension bike with 3 speed rear hub and tentatively went for a road test, and as you can imagine I was taken, Hook, Line, and sinker!!. in the famous words of Gary Barlow "Absolutely Fantastic". So on the good advice and recommendation of my dear friend and a couple of informative emails from Cylotricity and then an online order was placed for the Basic 250w 700c 36v front hub kit (less battery) and happy to report it all arrived promptly the following day. Thanks Guys!! Great Service. A++++ After the installation onto my newly purchased 1996 Trek 720 Hybrid all was ready for the final piece of the puzzle! But after being unable to purchase the 10ah bottle battery from Cyclotricty ( out of stock!) I hatched a plan to design my own 3d printed ("Hot Shoe") bottle mounted Bosch 36v 4ah powertool/Mower battery pack with the future intention of if satisfactory purchasing one or two more to extend my range as these are so small and light enough to be carried in a saddle bag. Perfect!! Well I am very happy to report all is well and since fitting the kit I have been out cycling every single day. :-) All I will say is that if anyone one is even in the slightest bit interested in building a kit DO IT!!! But as with all things Do Your Research first! and join this group as there is a wealth of information here and as is with most things it can be a potential mine field. Hoping this is of some help! All the very best, JJB
