The only two accidents I've ever had on a motorcycle were low speed manuvers in heavy rain when I got caught by a shower.
On a bike just riding on a slippery road is terrible and wading through umbrellas, getting splashed by cars in traffic, rain in the eyes.
Riding on two wheels makes you extremely exposed - ebikes are just shit motorcycles (especially self built ones) and have a higher accident rate statistics from what I can tell.
If you're not aware how risky it is compared to a car you are you are being delusional.
