Is it possible to set the required torque and maximum efficiency range by selecting your own nylon gears with a different number of teeth on a picrelated motor?
Is it possible to install other gears with a different number of teeth and are there any for sale? Or is there always one 1:5 reduction which is completely insufficient for driving in hilly cities with 29 wheels?
For example, I need the picrealted motor not to overheat at all when driving at a 10% slope on a 29 wheel, even if this will lead to the fact that on a flat surface the maximum speed will decrease to 25 km / h or less.
If I can't install other gears for require level of reduction, then I can only change it by installing 16-20 inch wheels, which is also completely unsatisfactory.
The mid-engine is completely unsuitable for me because it uses the resource of chains and cassete that are not protected from abrasives and require constant maintaince, while nylon gears are in a closed lubricated bath and do not require maintenance except for replacement every 10,000-15,000 km.
