I am selling my electric bike with a 250W legal mid-drive motor and 90Nm of torque, on which I have performed the following upgrades:
1. Front and rear brake discs of 200mm and 180mm, instead of the original 160mm
2. Suspension seat post
3. Replacement of the original 46T crankset with a 58T one, to avoid spinning out on descents or on flat ground with high assistance
4. Second 504 Wh battery, in addition to the 386 Wh one provided
5. Tannus armour in the rear wheel for puncture protection

Bike paid 2,099 euros plus approximately 800 euros in upgrades. Selling for 1,450 euros, negotiable.
