A bit reluctantly to post this as I am a bit embrassed for asking for advise then not listening to it, but I think should post it as an example of what happens when you don't listen. I went and got myself a KD-21C because I messaged the seller and he said it would definitely work so worst case would be sending it back for a refund. Well, it didn't as Woosh said, it didn't even power on, the problem then is my bike was dead after I swapped the original back in. It would power up but whenever I try to draw any power from the controller (lights or activating the motor), all the led lights started flashing. The manual says brake abbomality but it doesn't have any brake sensors. I tried all sorts to try and get it working and the conclusion was I must have fried the controller. I then proceed to checking the bottom bracket to make sure I know the sensors are going to work with whatever new controller I go for. I then found this: It looks like whoever installed the bottom bracket didn't care about the wire and damaged it. I repaired it, connected everything back up and everything is back to normal! Even more worryingly, neither the bottom bracket or the cranks were torqued up properly, very poor build quality. It was the red wire that has the insulation cut through so it must be shorting to ground causing the error. When I unplugged the Led, I must have somehow dislodged it enough to cause the problem. I think it's best just to leave it all alone for now. None of this stress if I had listened!

OK, so sounds like 1 and 3 wouldn't work either and 2 wouldn't solve the problem of the intrusive pedal assist. I am pretty sure the pedal sensor does torque as it's integrated into the bottom bracket, but I can't be sure until I take the bottom bracket out. Plan to do it this weekend when I am putting a new crank on. What controller would you recommend if I go option 4?

It's a KD-59E KD-59E

My led display is off a 5 pin Julet connector and Lishui say it should work with a key-disp. I know it might not work but for £25 it is the cheapest option. Do you think it is worth trying?

I have a Planet X E Urban which is not the most common bike out there. I think all the ebike compnents are just standard Chinese parts though. It has a Lishui LSW06-MIN1CFSB controller, a standard LED key-disp display and an Acer Xplova rear hub motor on a 36v battery. The main thing I am not happy with is the way the pedal assist cuts in and out. I think it kicks in too strong and it's like an instant cut out when it hits the speed limiter. I prefer it to be less intrusive. I did a bit of reading on here and think there are 4 options to change these settings: 1. Replace the led unit with something else that allows some setting changes, I think a KD21C will work? Not the preferred option as I like how simple the current display is. Having an additional LCD on the bars is just too much clutter for me. 2. Buy a Lishui programming cable 3. Buy one of those Lishui bluetooth adaptor off Woosh Bike which I think should work as well? 4. Upgrade to a new controller with a suitable display and programming kit. My preference is option 4 as it would open up all sorts of fiddling capability which I would really like but will be the most expensive. I am also not sure how locked down the current controller is which will reduce the likelihood of options 1-3 working. What do you think is the best option? Another question is to do with where the settings are saved. If I plug in let's say the KD21C, change the setting and put the original display back, would the settings stay or would it revert back to the original?

I really think it's difficult to get close to the value it was offering at the time which is why I decided to keep it even with the battery problem. Talking about the sag, yesterday, I decided to have a look at what type of controller it has. It's a Lishui Lsw06 which I think is quite common after looking it up. Also realised the pedal sensor is built into the bottom bracket so it must be doing both torque and cadence. I always wonder how I get instant pedal assist assuming it only sense cadence. However the biggest discovery is they basically stuffed all the cables into a ball and shut the lid so I unplugged everything and had it all tidied up. On today's commute, the battery sag seemed to have gone. At a point, it lifted up my front wheel which had never happened before. I also got to work and back home in record time. I thought the battery would have taken a hammering but I actually used less than normal after doing a post ride measure. So there must have been a dodgy connection due to their poor cable management that I fixed by unplugging everything and plugging them back in and organising it with some cable ties.

Unfortunately, they don't sell it anymore, can only find it on webarchive. E Urban I think the main reason they stopped selling it is because they don't have a clue what they are selling. I asked a few questions pre-purchase and they couldn't answer any of it. It's only because I know their product are always quite good that I took the gamble. Mine still have a problem with the battery where a warning light flash when it's fully charge but it doesn't affect its function. The battery also seem to behave well other than having a bit more sag than I would like. I think it is just a BMS problem. It's been back with them and they basically offered me a full refund as they don't know what's wrong with it and couldn't get hold of new battery packs. When I spoke to the mechanic looking at it, it seem like a lot of these were getting returned and they obvious not making any money from them because of that. It's got 2 years warranty so I will just keep using it and make a decision if I want a full refund just before the 2 years is up.

Hello all new to this forum. I joined based on recommendation from a mountain bike forum that I frequently visit. I bought my first ebike back in February which is a Planet X e urban. I have been a keen cyclist for years and been a fan of Planet X with this being my 4th bike from them. I have to say I knew nothing about ebikes and I bought it just looking at the price and the non ebike components which I have to say is excellent value for money as usual from them. It also benefit from the battery being hidden in the down tube as I dislike the untidy battery bulge on the downtube. I got into ebikes because I have been wanting to resume my commute by bike to work. I have done 2-3 years in London and another 2 years when I was in Swindon, but I never really managed to sustain a cycle commute since I moved to Sunderland. It's just too much hard work because of how windy it is here. I always ended up wanting a shower even after just 6 miles, it also ruined my weekend rides because I was simply too tired after a full week of commutes. People would just say I need to get fitter but I don't have the time having a busy work and family life. This is why I bought the ebike and it's been great. I can ride in in my work clothes and my weekend rides are not affected by the commute. It's also great for towing duty. 2 kids in a bike trailer is hard work on a normal bike. I have to say I have a habit of fiddling around with bikes and I probably spend more time doing that than riding. The forums' been a great help with the problems that I see with the bike and ebikes open up a whole new world of fiddling that I am looking forward to. I think most of my problems / future fiddling is already covered by old threads but I will post if I come up with something unique. Obligatory ebike picture doing towing duty:
