Wondering how punchy is the Fazua ride 60


Hi i almost ordered a roadlite on 2-3 years ago, but after reading a reviews mentionning that you had to open the battery compartment to switch the bike i decided that this was just too ridiculous.

So first i m wondering if this problem had been solved ?

Also i m wondering how punchy is the Fazua 60, how much torque ? what is the peak power?
How fast would it climb a 10% slope assuming the driver provides 200 watt, I remember doing basic estimation for 10% and 100 total weigth at 25km/h with a 10% grade, and the result was around 899 watts,
