Please help required,electric bike total breakdown

[mountainsport]

Hi all,

Went out for a ride on a full charge of battery yesterday,rode about seven miles in total,approximately six miles of that was done on the flat the remaining was up a slight hill incline.

The problem is when all of a sudden the bike had stopped suddenly at the top of the hill for what ever reason,i dont know. Then i dismounted the bike and walked at the same time pushing the bike to the side of the road,whilst doing so and with the power to the battery switched off, i noticed that the motor was dragging a fair bit,guys it was so bad that i had to even change into an easy gear to pedal down the hill and if i had stopped peddling the bike would have come to a stand still within seconds,that's how bad the drag was.

After,getting home i recharged the battery straight away just to make sure that the battery was accepting the current,then after i had switched on the ignition key,and nothing happened no power at all to the motor for it to move or spin.

I was told to disconnect all the wires that were connected to the motor,after doing so the problem was still there, a strong drag even in both directions which was manually done with my hand. The wires/cabling to the motor seemed ok and intact,i also investigated the brakes pads and disc, they were also ok.

To summarise,no power to the motor and after disconnecting all the wires,there is still a drag on the motor/wheel.Has anybody experienced this type of situation or what do you think could of happened? What do you all think is at fault the throttle,controller,battery,motor or the cabling throughout?

I am so disappointed at the moment because i spend a lot of time looking after the bike including all of the electrical components.Can anyone please help to give me some insight into what went wrong and if you can't help at all in anyway thanks for reading .

I can't help, but those that can will want to know the make and model of the bike, and the make of the motor if it's stamped on it somewhere.

Hi If you have disconnected the cable to the motor then the fault is with the motor or the cable going to it sounds like the wiring has shorted out is it a direct drive motor or a geared one

Without knowing what bike you have and what your history of problems is that you mentioned you had, it's impossible to help other than to say that if your motor is stiffer than usual without the wires connected, the problem is either coming from the last wires to the motor or it'ssomething inside the motor. When you say that it's stiff, is it notchy stiff or smooth stiff?

Hi Mountainsport.

Looking through your previous posts am I correct that you are talking about this bike.

LifeCycle Mountain Sport Electric Bike

I think your first port of call would be to the shop and find out if it is still covered under warrantee.

They have a contact email system on the site.

p.s. You could inform them that you are member of this forum and invite them to become a trade member.

Hi Yes it is a geared motor which has a free wheel so no drag in forward motion will have drag if you try going backwards so it Is mechanical inside the motor

Just a thought, if you have the bike mentioned in an earlier post it appears to have hydraulic brakes have you checked that they are both free, obviously this will not account for the lack off power to the motor but sometimes the obvious can be overlooked. Good luck with solving the problem.

Any joy with this, mountainsport ? Losing use of your bike is a serious pain in the proverbial if it has to go off for repair. You have my sympathies on this one !

Hi Guys,

Still no luck,checked the brakes,the drag is still there in both directions when wheel being spun, which feels very stiff and most definitely not smooth at all d8veh, and yes it does feel notchy thanks for that. With all due RESPECT! to you all,regardless of the type of bike or model,i do understanding that there are common faults on particular make or models,but this type of situation that could happen to any specific ebike,and obviously if poorly designed and made of cheap electrical/machanical parts. I am just curious to know what and why this had happend in the first case. Having a wild guess it's either the controller the motor or a combination of both.

Anyway,thank you all so so much for your valid time, support and also i will get back to you asap informing you what really had gone wrong including part/parts replacement.

Mountainsport. THANK YOU.

It's only when you take things apart and know what you're looking for that you see how things are really made I guess.

Whenever something expensive breaks on me (domestic appliances being the most common analogy) I am constantly reminded of built-in obsolescence in so many things today. Obviously it may not be the case here but I'm sure you know what I mean.

Very expensive Cuisinart kitchen appliances have been my biggest disappointment in recent years - every one including new-for-old replacements from John Lewis has fallen apart inside 3 months. I think they were meant to be admired in show kitchens and not actually used ! Bosch washing machine was another - complete rubbish was never right and put me off even looking at a Bosch bike (which is probably wrong because no doubt completely different assembly lines etc etc but anyway !!). Dell laptops ... office full of them were always falling over.

But anyway - hopefully it'll be something straightforward and fixable and do keep us posted. Best of luck with it.

If it is 'notchy stiff' then there is a good chance of a short in the phase wires that link the battery to the controller.

Cheers Alex sweet of you, i will do,i can at least tell you for sure that the motor has completley gone now in other words it's had days.

Hi you Have A geared motor with a free wheel inside if the cable was shorted out or damaged in any way the motor would still free wheel in one direction so you have a mechanical problem inside the Motor

That may be, but if you want me to be able to help me, you need to tell me exactly which motor you have, or at least which bike, otherwise, like from everybody else, you'll just get wild guesses.. As a start, if it's got a disc brake (which I don't know because you haven't told me), remove the caliper to completely eliminate it as a potential cause. Why don't you want to tell us about the history of problems you had that might have some bearing on the matter?

Hi Mike,

Please remember that all the wires coming from the motor are disconnected from the battery and the controller, still a drag on the wheel. Thank you.

Hello d8veh,

Thank you for your genuine concern,and yes the brake calipier has been removed and tested also this has been the first major problem that i've had with the bike apart from the wheel puncture which is very highly and likely expected from a rider and definitely more acceptable. Basically, d8veh what could have possibly gone wrong during a simple ride up a slight gradient.

I think the clue is in the name lol ...

Battery is uprated to 17Ah this year but presumably the motor is the same (?)

I'll leave this to the rest, seeing as you don't want to tell me about your bike.
I hope you get it sorted soon.

Just the motor manufacturer would help don't refuse the wealth of knowledge available from this site PLEASE.
