Carrera impel im-3.1 not turning on

[Wayners]

Oh.
Reminder to self. Avoid.
Seems a few bikes on eBay with battery dead being a problem. One near me for £250 and looks like new. I'm itching to get my hands on one to try and fix but I'm thinking its just a impossible task. Maybe why the stores are struggling to fix so many.
Crazy when you think of the costs to purchase a bike, yet it's a box of tricks.

The standard Chinese bikes are pretty easy to fix. It's the ones that use comms between the battery and controller that are very tricky. That includes most of the halfords Carrera ones.

Any basic generic tpye of bike is easy to repair if the battery is working and the motor is ok, usually £100 will get the bike back on the road with a KT system.
I have noticed KT parts have seen an increase esp on Aliexpress but they are still imv the go to system as crapwave are just that and lishui aren't often supplied non OEM and then they often need programming if one doesn't want the crap speed control, Woosh for example can programme them for either speed or current control. Where as with KT one can do both via the settings though have never heard of any one saying they prefer speed over current control when using a KT.

Just going to try to switch out a hesc Carrera Vengeance system totally Awaiting the Kit to arrive. Always seems to have a problem with its pedal crank sensor Once it ripped the wire off by rotating Took Halfords 3 weeks to fix & as for the wifes Raleigh Stow E Way 5 months in has spent more time back at Halfords than with us Only just sorted by giving her a brand new bike Not sure Halfords have any really skilled E Bike technicians One said to us take the bike somewhere else :-( The actual motor cable on Hesc seems to be totally different from the KT motor leads Purposely gone non standard to make repair difficult & the cost for parts extremely expensive

The Suntour motor connector is completely different to a standard Chines 9 pin one. Best way forward is to buy a 9 pin motor extension lead and cut off the end with the male pins and solder all the wires to the Suntour cable.

The Kit I ordered has arrived in the last 30 or so minutes it includes a wheel with a 350 watt hub So will be trying the total kit Its for my son who travels 9 miles each way to work so the 350 will give better pull up some of the steep hills around his workplace I ordered the wheel kit because I wasn't sure that the wiring of the Hesc hub would be different Quite impressed to have got the Hub from Germany via Fedex in two days though for £206 I may go the route of listing all these expensive to buy Hesc parts on Ebay to recoup some of the costs in this build I only dabble as a hobbyist with ebike stuff Don't fancy setting fire to my shed yet by connecting the wrong wires together So the kit is jolet connectors mostly even down to the controller in the battery carrier

350w hub or 250w one won't find any difference hill climbing, for torque motor rpm, current and wheel size make the difference along with gearing. The wattage is really neither here or there.

At the moment I have set him loose on My Eleglide which appears to be mostly lightweight Aluminium unlocked speed not sure if its 350 or 250 watt but he seems to be enjoying it a bit to much I just hope I can persuade him to give me it back Its only a summer bike really for me Popping to the shops I use a really old coyote 20 inch foldable 24 volt front hub bike as it is so easy to store and get out when required I purchased that dirt cheap with a battery that was not even charging for £65 (bargain of the year ) New upgraded yosepower battery cost twice the price of the bike though At a pinch I can actually get it in my saloon car as that is Ali frame with steel front forks and pretty light

The motor won't fit in the frame. The Suntour one has a different axle arrangement. It would be better to get another bike as the donor if you want to use the whole kit. The 350 w kit doesn't have any more power than the 250w one. In fact, IIRC, the 250w one climbs better due to it's lower speed winding.

With the Suntour one should simply keep the Carrera frame and upgrade the electronics , keep the motor connector intact as it is and simply join the wires at the motor cable end to the controller.
Others have gone this route and simply connected colour to colour without issue , though one should make those connections temporary to simly test the motor works 100% correctly before making permanent solder connections and insulating.

I will look at that route As I take it apart making sure I take photos of wires at each connector point before doing anything else I did purchase some of the new solder connectors that you just use a heat gun on solderseal heatshrink butt connectors .Which may well come in handy If this route seems easy to do But the controller has a built in motor connector plug which fits inside the battery carrier Hailong controller Which I have a large battery that fits I was trying to keep it as idiot proof as I could and the less I have to alter the less I could make a mess of I think the Kit is expecting to see a set of inbuilt settings on the controller as in wheel size and other parameters Been told the kit is almost plug and play If the wheel from the kit fits the frame I will probably go for the total kit Maybe when I get more experienced I will start the joining wires Hesc motor diagrams/schematics are not easy to actually find online I feel happer stripping a motorbike engine and rebuilding it than ebike modding

Going back to the original thread. I took my bike back to Halfords who said the battery had gone into hibernation mode and couldnt be reset out if it! So they have given me a new battery as it was only 18 months old and under warranty. Dont hold out too much hope of keeping this bike for 10 years without spending loads if cash on it!!!!

I watched a youtube video on a swedish Battery doctors channel Disconnected the BMS from the battery after undoing the cases then using a multimeter drained the BMS of any residual current & it worked This was after trying to charge the cell packs up that were unbalanced while in place which he thought would work but didn't It was fascinating stuff but beyond the scope of people without the expensive equipment to charge these individual cells or cell packs that become unbalanced and dained Hafords aren't very good at fixing ebikes I think they don't have expert technicians as most of them are about 20 years old or younger in their bike hubs

You don't need special stuff to measure and balance batteies. You can normally do it with stuff you have around the house or get something from Ebay for a couple of quid. Unless you're really good at figuring things out, you need a bit of knowledge and understanding that can be given here if you're interested.

With a hesc bike one throws everything away bar the battery and motor, any controller in the battery base one removes the guts as it is useless and of no use .
The battery can be kept and used but would need the BMS taking out and a generic BMS soldered in instead, a competent person who can solder can do this.
The controller if a semi integrated one is used is simply gutted out and a pair of power wires extend to exit the housing , these wires simply then connect to a new external controller placed in a seat bag or top bar bag.
