Sounds a bit suspiciously wrong, but au contraire it is possible. EMBN did a recent video on mid mount motors but really really missed the the most obvious motor the TSDZ2 ( who ever was advising them must be at at least 3 years behind the rest of us ). The TSDZ2 is a full torque assist, can be bought as a 750W ( which is about the same as the latest gen engines from the likes of Shimano despite the 250W its supposedly putting out ) 100NM of torque with a pedal cadence when modified ( more later ) of around 95 rpm which is right up there, all for about 325 notes.
Its not for everyone to go down this route and if you have an old 26er sitting in the shed, then leave it there. But if you have a 29er, perfect. If you are think you could buy a 29er and fit a TSDZ2 then also forget it, add a grand to the total cost and you could get a first generation EBike off the likes of Ebay which is singing and dancing without the hassle. But if you have your pride and joy 29er or 27.5 sitting looking forlornly in the shed and the mud of the winter trails is putting you off, then think again.
No a converted bike is never going to be as good as a factory unit but if you think it through and take the small pain ( such as lower ground clearance ) than your original bike, you can build a top notch Ebike around the 20 - 22kgs all up dependant on your bike of choice. The TSDZ2 is a 2 hour conversion with only minimal wiring skills needed, has cheap and plentiful spares and sssshhhh can be " uprated " to be really really good.
Why the need to tinker with the Motor, from the factory they are 36volt or 48 volt units, both setup to be sold in the millions to Chinese commuters which just want ooomph to get there at a very low cadence, as standard your wife and mother in law will love them, but if you are a regular rider then your cadence will be at about 80rpm +. Once you hit that rpm the motor will begin to back off its power, its just the way it is and an easy fix. Buy yourself a 36 volt unit, fit a 48 volt battery, change a byte of programming and voila you have a 500W 90rpm cadence beastie.
Then you can go one step further, re progam the unit with the latest FreeWare for the motor which has FOC management of the motor giving much better control of the motor which gives about a 20% gain in battery life, with greater torque, take you pick of a full display unit of either monochrome or colour or a small handlebar unit and you probably have a better display than most, as good as most, all for less than 500 notes.
There's lots of questions to be answered such as batteries ( yes we run 360Wh batteries which cost us less than 95 notes to make and are tiny 150mm x 70mm x 80mm " bricks " which gives us about 2 1/2 - 3 hours of joyous mud plugging " fun". Do ask the question and I'll endeavour to fill in the gaps and the learning curve.
