750watt of 24V DC motor power is exactly 1 mechanical horsepower. I will say this unto thee! One horsepower in a road bike front wheel is nice to have. Especially if those watt where geared toward speed on a seperate chain. with a 126AH battery and a average 25amp (600w power) it will have a range of 5 hours. Maybe 25amp is pushing it. 15 amp cruising.
