A little improvement

Dear people, I have thought a little improvement for my SLA batteries: Connect in parallel with them a large-capacity electrolytic capacitor, let's say 5000 uf x 80 V, the purpose is to improve the peak current to the motor, What do you think?

It's a good idea to have a big cap on your power supply (except for the inrush currents when connecting power), unfortunately, unless it's a supercap, your "normal" capacitor doesn't store enough power to make any difference. One Farad is one amp X one volt.....about one watt/second of power. Your 5000 uF cap is five thousandths of that, so at 36 volts it would contain .180 watt/seconds of power. A 500 watt motor is typical on an e-bike and uses 500 watt/seconds of power per second.

Afraid you wouldn't notice any change.
