Isn’t that the same for all bikes??? Or just E Bikes????
I think the logic is we all know a bike can travel well beyond 25kph, often in specific circumstances, well recognised by all. Downhill, for instance everyone knows and reasonably expects any bike to be travelling significantly faster....and people subconsciously make adjustments in the reactions accordingly, based on lifetime experience. It's a good rule of thumb most people will work to when viewing a (what looks like a standard) bike on the flat, it's going to be travelling at a speed we reasonably expect it to be travelling at, based on that lifetime experience. It's not a cover all situation but one most people will cope with easily. Start changing the very basics of that and perhaps you end up in trouble.
This is just theory of course and I may be wrong, but it seems quite sensible to me. As stated up post, if you want something faster, perhaps its be more appropriate to buy so ething more appropriate, a scooter, motorbike or similar ?
My own opinion on the 25kph / 15.5 mph limit ? I'm fine with it, if you up the speed limit, you simply reduce the distance achievable by the battery...and let's face it, you dont get great mileage anyway, especially as a battery ages a bit.l
