Lurkin
100 kW
1st build, using a mountain bike and adding assist for a commute bike. Not an engineer etc, but have assistance from those who are.
Bike: Trek X-Caliber (29er)
Parameters:-
350-500w hub motor capable of being electronically restricted to 250w (to get a decent amount of torque)
Capable of moving 115kg bloke on two 40km stints per day. Distance capacity is more important than speed > 25km per hour.
Must be capable of (the assist) being speed restricted to 25km/h
Preferably use a torque sensor if possible?
Was originally looking at a BionX kit for simplicity, however the $3k price tag rendered it out of the budget. I probably looking to spend in the order of $1500 AUD.
Havent completely written off the idea of just buying an entire bike, but then I wouldn't learn anything and would be in the same position when it requires replacement.
Really looking for a bit of advice as to what kit to go for and what parts are required to make it practical. I have been looking into the BMS battery kits but really unsure of whats required to make the restrictions work reliably.
the kit I had in mind is https://bmsbattery.com/ebike-kit/402-bafang-bpm2-48v350w-rear-driving-bike-conversion-kit-ebike-kit.html
unsure of which battery is best to go with. Probably was going to get a bottle style battery to fit on the downtube.
I'm also not sure if direct drive is the go or the planetary gear route. I understand regen is only possible with direct drive, but unsure as to whether this is really worth pursuing (given the distance I need to travel)....
I'm assuming this torque sensor would only be useful for a crank style set up ?

any advice would be great to get started.
Standardised info:
City: Melbourne
State: Victoria
Country: Australia
Desired max speed on level ground: 25 km/h assisted , higher unassisted
Desired max range at what cruising speed: 40km each way (commute to work), 80km per day in total. Can recharge in between, in a perfect world I wont need to.
Preferred bike wheel size, or wheel size of bike you want to convert: 29er
Brake type of motor wheel: Disc
Rider weight: 115kg
Terrain. Exp: mostly flat, some short hills under 20% grade
Budget: AUD$2,500 was the original budget, but looking to be less than this.
