That's a really helpful reply, thank you very much.

I have a Swytch mk 2 ECO system fitted to an old Dawes hybrid bike which i've used for my 5 mile commute since Nov21. I bought it as a cheap stepping stone into ebikes. Overall I've loved the system but now it's showing its age and i'[m wondering whether it is faulty or this is the reality of ebike batteries. At first I could go both ways at power level 3. After a while I needed to charge it at work to get both ways. It then steadily decreased and I could only get power 2 for commute and then power 1. Now it does a thing where the unit turns off despite having 3 battery bars left. If I recharge it and turn hidden battery switch on/off then it comes back up. I guess I have recharged the pack almost 1000 times and its just passed its life expediency. I'm planning on purchasing a premade ebike through cycle2work but i'm slightly concerned about the idea of a 2 year battery pack life span. Will I be able to buy replacement batteries in 2/5/10 years time? Is my commute an awkward distance for the Swytch so it meant I was recharging too frequently and that an initial bigger battery would have last longer? Any thoughts or experience would be appreciated.
