If you crashed on the side where the wires exit the axle, that is almost certainly where the problem lies. Very common, soft insulation is scraped against hard metal, shorts or complete cuts frequently occur. Should be 8-9 seperate wires, three thick, 5 thin, maybe one-two more. Shorting any one of the primary 8 could cause what you have, several combinations mean major repairs required.
It is odd that you get all indications of power, no error messages, and it just does not work. Focus on throttle and pedelec connectors, completely disconnect each one and test, seperately.
For instance, if I turn my bike on with throttle partly or fully engaged, nothing will happen, until I move throttle fully off, then back on again. If throttle was bashed enough to move the internal sensor, you could have similar problem without it being obvious.. So remove it from the equation, unplug it. If you have a spare throttle, test with that.
Also, if you have lights, horn, radio, radar, anti-theft, etc., disconnect EVERYTHING not absolutely necessary to make it go, and test.
If you do not have a DVM, get one, essential ebike test equipment. 2 digits past the decimal are ideal, but not mandatory. Use a fresh battery in the meter.
I do not understand the concept of looking at a problem without doing a complete diagnosis.
One of the reasons I know so many ways to solve a problem, it when people, like YOU, report back on exactly WHAT was causing their particular problem, and how they fixed it. Only about 10% ever report back with this vital information, which helps the entire ebike community.
Be one of those people.
