Ok thanks I have a few electrical engineer friends so I think I'll ask them for their help trying to repair it by soldering it first, that seems like the most simple solution. But its nice to know I can upgrade to an LCD with a new controller in the future, I thought that option would be lost for my bike model. Thanks so much for all your responses!

Hi, Thanks for all the info! I didn't know the new one didn't have a controller. I tried swapping over the top part of the cradle and cleaning off the pins so they move smoothly but unfortunately it still wouldn't start. so I took the controller out a little to look closer at the wires and noticed (I think) at least one is broken (the yellow wire in the pic below): I imagine this could be the issue? I'm also guessing it could only be fixed by soldering (a skill I do not possess). Do you know if a new generic controller would be purchasable anywhere?

The current wires connect into the old cradle like this (below): All with connections like this from the wire on the cradle to the wire on the bike: (these don't pull apart -or at least not easily- as far as I can tell) One wire goes to the pedal sensor, one to the motor in the rear wheel and one to the components at the handle bars. The collection at the handle bars is connected as pictured below The new cradle and wires look like this: Sorry for so many images, I didn't want to leave anything out.

Hi all, I have a Greenedge CS2 ebike whose battery (36v, 9Ah, 2 pin - old style) stopped working as it was quite old and had been dropped a few times. So I ordered a new battery from eBikes direct (after a lot of faff), the only one they had was a 36v 11 Ah (still 2 pin old style). When it arrived in the post it came with a new cradle. Originally, I wasn't going to install this new cradle since the new battery fit in the old cradle (which is rated for 7-15 Ah so should be fine for both 9 Ah and 11 Ah battery), but when the new battery is in the old cradle the connection is very bad and it often cuts out or doesn't start at all. So I need to change the old cradle with the new one. I though this would be an easy change over until I looked at the two cradles more closely: The old one (currently connected to my bike) has three wires between it and the bike, but the new one only has two wires. And the connectors between the wires look different. Does anyone know how I might first disconnect the old cradle, then connect three wires from the bike to two wires on the new cradle? I've tried asking eBikes about this but they are very slow to respond (as I found even when trying to buy the battery). Any suggestions would be much appreciated, I can send images if that would help.
