2000w E-Bike Conversion Kit + 52v 30ah Smart Battery (Bluetooth App)

Off the line it pulls hard from a standstill without you touching the pedals — a hub motor this size makes its shove low down, so it is the pull away from lights and up steep starts that surprises people, not the top end.

On hills the 50A BMS is what matters. A 2000W motor asks for about 38A, and this pack is built to give 50A, so it does not sag and cut when you hit a long climb. A weaker pack browns out exactly when you need it.

At speed it will sit at 45mph on the flat. Realistically you will spend most of your time between 25 and 35mph, which is where the range figures come from.

Range honestly. 26 to 37 miles on throttle alone, no pedalling, with a 75kg rider on mostly flat ground. Pedal along on assist and 45 to 55 miles is normal. Ride it flat out everywhere and it will be nearer 20. Your weight, the hills, your tyres and the wind all change it.

The app is the difference. This pack pairs over Bluetooth and reports every cell voltage across all 14 groups, temperature, cycle count and live current draw. A lithium pack rarely fails all at once — one cell group drifts and range quietly drops. Here you can watch it happen and ring us while it is still fixable.

Tools you will need: two adjustable spanners, an Allen key set, scissors, and tyre levers if you have them.
