I have two bicycles, the bicycles are similar. The two bikes are hybrids.
The old bicycle is this:
The new bicycle is this:
The old bicycle has 700c42 tires, the new one has 700c35 tires.
The old bicycle has 24 speeds, three chainrings, eight threaded sprockets and a motor. The new bicycle has 18 speeds, with three chainrings and six threaded sprockets.
On the old bicycle I have a ninecontinent 9c engine, I think it's the 2808, the engine is old. The old bicycle has several things to fix, it has cracked rims and that's why I don't use it. The rim of the tire would have to be changed for another one and more things fixed. The motor is 500w without gears, the battery is 47V (13S), the maximum speed in assistance is 42 kmh, but I have it limited to 25kmh, here the maximum legal speed in Spain is 25kmh and speeds of 40kmh I They seem to be dangerous.
The old bicycle has saddlebags, where I can carry things in the back, in the back, in the saddlebag I have the battery and the controller, the motor is rear, the battery is 13s7p with 3350mah sanyo cells, the battery is 822Wh. The bicycle has a problem with the weight, it weighs 25Kg, it weighs too much, and much of the weight is at the back, riding a bike there is no problem, if the bicycle is stopped, you tilt it a little and hold it by the handlebars, the front wheel will move. lift it up and you have to hold it from behind, if you want to put the bicycle in the car it's a problem, it weighs too much.
The new bike weighs 14kg, it has a normal weight and there is no problem when tilting the bike, there is no problem when putting it in the car.
The problem with the new bicycle is that where I live there are many hills, when the hills come it is very difficult for me to go up the hills and after some hills I end up exhausted, with no desire to take the bike again, if I use the bicycle on flat ground there is no problem if I go slowly from 10 to 20 kmh.
I am overweight, I weigh 120kg. I have a problem with all bicycles, after a few months or years of cycling the spokes of the rear wheels of all the bicycles break, on the old bicycle the spokes have resisted and cracks have appeared in the rim of the rim.
The problem with the power, I have the controller set to 17A, since with more amps it seems that the motor has a lot of force and the motor does not assist well at high speed (15-25kmh). When hitting a hill and slowing down to 10 km/h, the engine feels like it's running out of power, which forces me to put more force on the pedals to go up the hill. I have looked at the ebikes.ca simulator, as you lower speed the efficiency decreases and the amount of power generated by the motor decreases. I have looked at the simulator with a 36V battery with more amps in the controller, the power curve is the same as at 47V, but the 47V curve has a higher maximum speed, 32kmh for 36V, 42kmh for 47V. Is this correct simulation? Doesn't less volts and more amps give more strength to climb hills?
The controller is a kt with an LCD screen3, 36 and 48V, the controller is 25A.
The battery is rectangular, do you recommend I put a bag and put the battery in the central part of the bicycle or under the handlebars of the bicycle? It would be to distribute the weight, I don't have the bag, I would have to study it.
Would it be good for me to change the rear engine for a front one? to have the weight more distributed.
Would it be good for me to change the motor for a 350w front cute q100h with gears? Is the cute q100H motor in the ebikes.ca simulator or is there something similar? I would like to compare before buying.
Would the 201 rpm q100h cute be good for me if I use it at 36 or 48V?
Is it better to use a 36v battery than a 47V one?
If you do not change the engine. Can you see this rim for repair? https://www.bike-discount.de/es/dt-swiss-535-llanta-de-28

If I change the engine, what power would be recommended? When I ride a bicycle I want to pedal all the time
