Cube Stereo Race Hybrid 160 HPA Electric 20" Mountain Bike E Bike 27.5 Wheels

This auction is for a Cube Stereo Race Hybrid 160 HPA Electric Mountain Bike E Bike 27.5 Wheels 2016 model. 20" frame size which is a medium sized bike. I'm 5ft 6 " and I have the seat dropped. Unfortunately there is a problem with the seat dropper, and I'm unsure how to fix it. I think the cable and the push button mechanism is loose. When I bought this it was working. As I don't need the seat adjusted I've not bothered to fix this and I am unsure how. So please consider this as you might need a Cube specialist.
I have upgraded the pedals to Vault DMRs. They're new as I only just replaced these.
The battery still appears to hold a full charge, all bars  on the indicator appear when fully charged. I'm unsure how to check how many miles the bike has done, if you know let me know!
I don't have the manual and I bought this from someone else last year with the intention to take it off road but haven't done anything apart from a little road riding and park paths.
The bike in standard setting is restricted to keep to UK law, however it comes with the ability to be unlimited. Pressing the walk button will switch to unlimited mode.
Includes fast charger and key for locking the battery.
Overall condition is very good. There are some signs of use but nothing really worth noting. Before committing to purchasing you can view the bike but no free test rides.
