I would say it is quite doable, depending on the kit ... For a mid-drive kit, it all comes down to the bottom bracket (BB). If the kit will fit into and through your BB, you have a start. The next issue is how to deal with the torque? Some kits "crush" the BB shell to try to hold it all in place ...

Me, I'd look at the Tongsheng TSDZ2 kit and see if it will work for you. Battey goes on your bottle mounts. Motor contains the controller, so no messy external box with wires. Torque is managed with a small plate across the chain stays.

Has built-in TQ sensor and no throttle. It's pedal assist only (in the general configuration). Small display on the left bar. Select the level of assist you want and it adds power as you pedal. No throttling to worry about.

You can look them over here: TSDZ2 kit I'm sure there are dealers in the UK.
