Giant XTC E+ PRO.
I don't agree on that. I use bike abusively the same as my motorcycle and not treat it like porcelain. If the bike failed, then its components are not up to the stand. Then I will be away from cycling since it feels more like a leisure sport rather than practical usage.
Most bicycle components are not designed for use like an "ebike". There is no way to run away from that, Industry is getting better but the bike you have is a classic old construction, with 1.8-2mm thick aluminum parts across the board.
1. The bike chain can take a max of 200-230 Nm of torque (humans can put out around 120-150Nm of torque, as a reference).
2. The rear hub pawls are similarly specced at 230-250NM of torque. If you are in the wrong gear (or high gear) from adead stop, then you will have one of many failures
- Chain skipping. This is more a rattling sound than a bang
- Casstte skipping - rare but happens. You will notice teeth breaking. That may sound like a bang sometimes.
- The actual hub skipping - this is rare but may also sound like a bang followed by somewhat constant loud clicking or grinding sound
- Your motor skipping (yes, the motor internal clutch / pawls) are also limited to around 200-220 Nm - and at a larger gear you can exceed that. This is also a loud enough bang.
Overall, ebikes aren't motorcycles. You may not like this answer but that is the reality. In words I head from another bike manufacturer on this forum a while ago that have stuck with me - "
If you are trying to break something, you will succeed."
If you are looking for strong but lighter components, then we are effectively running up against physical limits of materials known to man. I mean at some point a 1.8-3mm thick aluminum or steel part (avg thickness of parts on a bicycle) can only take so much torque / beating before it breaks. Motorcycles on the other hand average around 8-10mm for most parts, including m10 bolts or higher, thicker steel chassis etc etc. Just basic physics.
If you are in highest gear and are abusing the bike, it will break - sometimes with loud bangs, and sometimes even worse - like frame failure. I would recommend knowing these generic guardrails for ebikes - and then tweaking your ride pattern accordingly.
