your spinning is pretty slow so your not going to get the most out of a mid drive. a torque sensing mid drive feels like a regular bike but it takes less effort. the harder you peddle the more the motor will help. your speed is from the gear choice and your cadence just like a normal bike. How much effort it takes is from the level of assistance you choose. so you would change the assist level to meet the level f effort you want to put out. on my bikes I have 4 levels. so I can go 20mph putting out 90 watts on the highest assist to close to 200 watts on the lowest level but I am still peddling the same speed and in the same gear.
