Can you hit that speed on a regular bike on a regular street? Can you break quick enough when people or cars get into your path while at that speed? E-bikes I see around here are operated by people who don't use the front brake and wipe out all the time at <20 mph. It would be fine if they just hurt themselves but they also run into pedestrians and cars, causing bodily harm and property damage.
