It's not nice to read sarcastic caustic comments aimed at a 81 year old trying hard but struggling to solve a problem, I'm sure most of the "experts" on here have taken a long time learning about everything to do with electric bikes. As I am so useless I have ordered a new bike so that I don't have to ask for help on this website which I fist used probably 10 years ago but at that time people were much more pleasant.

Oh my god, so much for the 25 pages of advice from A1. Thank you so much for your kindness. I have ordered one for delivery tomorrow then I'm hoping Xmas has come early for me. Bless you

I have checked everything. The selector on the handlebars works, the sensor red light on flashes, I have had a meter on the very small plugs on the controller red&black and turned the crank anti clockwise, nothing happens no voltage shows. The sensor disc with the magnets is in perfect condition so it looks, as if AI was right that the controller is knackered. I've resigned myself to the fact that I need to buy a new one but finding one with with the same connections is proving to be a PITA

Thank you for your reply but my controller is Brushed

Thanks for the messages. That's all beyond my capabilities and I think I would be better buying a good second hand one

I am 81 years of age but I do still try to get a little excersize. I bought this Swifty from Amazon 3 years ago. I go about 7 miles and ite been fine until last week when I turned it on evrything lit up but there was no power. IHaving heard a lot about AI I decided to try it. It came back with all of the information. Controller number B-WZKD3613KA. BRUSHED 36V 350W WITH PAS & BRAKE. I had already checked the crank sensor and brake sensor which appeared to be ok. AI listed lots of places where I could get one but none came up with the goods. I contacted Bikes. Co. Uk who I understood made the swifty but all they could say was we might have some next year. I'm really brassed off without my bike and need to get a controller

As I mentioned before I had a week away on holiday but before I went I called into a new bike repair place in Derby. They were very helpful but quite busy. I left the bike with them for a week so they were under no pressure to get round to it. The chap rang me back within the hour and explained that crank set I had fitted was not perfect for the job due to the curved rim on the inside of the crank which I had mentioned in my previous post. He explained that when tightening the crank set up it was fouling on the sensor disk and that he would grind down the curved part of the set and refit it. I asked him to do whatever was required to get my bike fit for use. I was amazed when he rang me within an hour and explained that what he had done had cured the problem, he had also carried out a check on the rest of the bike and it was ready for collection. When I collected the bike it rode better than it had ever done and I am elated. Thanks for the communications and guidance

Thank you for the reply. I am going away tomorrow fro 1 week and will try your suggestion with the washers, in the meantime I managed to get the correct battery carrier for my bike from Ebikes, they were very helpful and informed me that my bike is the Commute model if thats any help, I have tried to find more information without success maybe you know the secrets of finding the info, with there being so many variations its difficult. Kind regards, contact you when i get back.

Sorry my friends I don't think I explained very well. The number of teeth on the new set (48) is the same as the old one so the chain should be ok. Even when I take the chain off the crank it is very stiff. I have loosened the crank bolt slightly and everything seems ok. I very rarely change my chain set as I have no need to change gear on the route I take. I leave it on the biggest cog on the front and smallest on the back, set my electric to level 1 and everything operates ok

Hello again,, I wonder if you can give me the benefit of your knowledge and experience....I my last episode I fitted the new crank set and new pedals. I had difficulty in getting the chain on to the biggest chain ring, the guide would go over far enough to get the chain onto the chain ring. I adjusted the cable as much as I could and eventually got it on. I thought wonderful and went out for about 10 miles everything seemed fine and I reported back to you on the success. I was a bit off colour for a couple of weeks so didnt go out again. I then decide to venture out, on the way back The right pedal seemed strange, I stopped and found the new crank set bolt had come loose. I tightened it up as tight as I could and got although the crank seemed a little stiff. Before I went out again, I checked both pedals and crank sets for tightness and game another tightening. Now everything is very tight I can hardly turn the pedal. I have had a look on the internet as I didnt feel I could bother you but that was all about the bottom bracket which I found difficult to understand. I then rang a bike shop in Derby who asked if I had fitted a new bottom bracket and suggested that this could be the problem, which would account for me having difficulty in engaging top gear..I have looked for information on my bike Elife La Grande 26"| fold up bottom bracket but cant find anything and not sure what kind of bottom bracket I have I do understand some are pressed in some are screw in and I dare say if I have the screw in one I could replace that..I'm at a bit of a loss at the moment and feeling quite depressed.

I think I may have celebrated a little early. Went out on my daily 10 mile this morning and something didnt feel right with my right pedal. I stopped and found the new crank set had come loose. I happened to have the right size allen key and tightened it back up but now I feel very nervous when I go out just thinking about whats going to happen next. Should I tighten the bolt very tight maybe using a bar or is it possible to overtighten . Is there anything I can do to stop it coming loose again.... Thanks

I needed to buy a new battery carrier for my Elife La Grande electric bike. I tried all over the place to find a new carrier which would house the controller but was unsuccessful, the only way to get one was to buy a new battery where the carrier was included. I ordered one from Ali Express which was distributed from Germany. When it arrived the battery was fine but the carrier was not suitable as it didnt have space for the controller. I contacted the seller who immediately offered a full refund. subject to the item being returned to Germany. I realise I will have to pay postage but everywhere I look at different carriers it all seems very difficult to post the battery. Do I have to include a customs declaration etc,,I am very nervous about the whole thing, any help you can offer would be gratefully received.. Many thanks Russell

I have bought several bike computers but when it comes to fitting the sensor on the wheel spokes the allowed distance from the sensor to the magnet that fits on the frame is way to far apart, most of them say 3-5mm. Maybe I am not interpreting the instructions properly or there isn't one available. I would be grateful for any advice. I have a limited budget and Amazon have the Cats Eye Vero on offer at £29.

Hello again,, I am over the moon. I decided to try the new one for size and fit and bingo it fits fine, not touching anything. My new pedals arrived today and again decent quality. I sent 2 sets back to Amazon which were really poor quality. I am really grateful for your kindness and consideration. It is thanks to you for giving me the confidence to try. I will be going out on my bike tomorrow, not too far to start with as I'm wondering now what will be next.

Hello again. I should have mentioned that there is a sensor disc which the crank gets close to when in place, that was what I was concerned about. I slid the old crank on but never tightened it up to see how close it got to the sensor. Then I slid the new one and the space seems to be the same so maybe I could be lucky. there the raised lip on the new crank is about 5mm closer to the sensor than the old one. Tomorrow I am going to slip the new one on and tighten it up and see what happens. I do apologise for being a nuisance but I am desperate to get back on my bike 5 weeks ago my back tyre blew and I finished up falling off my bike. I broke 3 ribs which was very painful and then only thing you can do is take pain killers and rest. I am on the mend now but need to get my confidence back. I was at the time quite disappointed that although the road I was on is quite busy, not a single car stopped to see if I was ok. They might be morons out there but then after using this wonderful website and asking for help, everyone is so kind and helpful which has re-established my faith in human nature Thank you again

Thank you for the guidance, I am a little confused regarding the bottom bracket but will try to see what I can do. I have slipped the new crank onto the square axle and it looks as if its not catching on anything but of course In have not fixed properly in case I need to send it back if I can..

I received the new crank set which looks very good quality but it is slightly different from the damaged one. I have attached some pics. The new one has a raised rim on the inside face, other than that it looks fine, I'm just not confident if I should fit it or not . I hope I can as it looks so much better quality than the old one.... I would be grateful for your advise,, regards

Thank you so much for the information. I have ordered the crank set you suggested also a new pair of pedals, the will be delivered on Wednesday. Fingers crossed I can manage to fit them.

I have had my Elife for about 3 years now and its been excellent until today when my drive side pedal came away. On retrieving my pedal I attempted to screw it back into the crank but noticed the thread had disintegrated. I thought it would be a case of using a crank puller to take off the damaged crank but a new one and fix it but when I pulled the crank off the drive sprockets are part of the crank so I am going to have to replace but not sure where or what I should be looking for. Once I find the correct replacement I am confident enough to fix it . I called Halfords who were not very helpful and didnt seem to know what I was talking about. My bike I think is 18 gears, 3 different size sprockets on the crank and 6 varying size cogs on the back wheel. If someone could advise me I would be most grateful. I am 77 years of age so please be gentle. thanks

Once again thank you, these have been unused for about 12 months and then left in my garage so can I assume that they would be ok to place in the recycle bin as my recycle centre is 12 miles away

Christ, that is scarey..what is bms referred to above... I will definitely carry out the advice given and am grateful for all of the help. How long should I leave in a bucket of water for before disposing of them, where do I dispose of them.

photo of blown battery

I have a frog battery 36v 8.5 ah. The battery has blown out of the casing, prior to this it was working perfectly and charged normally. It has about 5 what look like plastic bags which I assume contain the battery power. I have tried placing very heavy weights on the casing but cannot get the contents back . If anyone has any ideas, if not then I am happy to offer the battery up for repair. Thanks

I have a 26" foldup electric bike Elife Grande which I think may have been purchased from Ideal World. I am 76 years of age and try to keep myself in reasonable order by going out on my electric bike most days. I only use electric when I need to and cycle about 10-15 miles a day. I want to fit a basic cycle computer so that I have a better idea of how far I have been, some days I feel better than others. I have bought several of them and sent them all back because the sensor which fits on the spoke cannot be more 5mm from the receiver but the distance between the spoke and fork/receiver is 4.5 cm. Does anyone know of a suitable, not too expensive computer that will fit. Thanks

Thanks for the reply, what makes it a little more difficult is that if I lift the bike up and turn the pedals the gears seem to change ok but as soon as I ride the bike the problem appears with weight on. I will have a look at what you have suggested. Many thanks
