get a Smart Helmet so you are more visible to other drivers in rain and fog. also installing lights on bike is a plus.
for most electric bikes its going to cost around 200 dollars for the bike kit + 200 for battery unless you build your own. (you’ll need a spot welder from ebay for 30 dollars the red ones i hear work well)
8000 watt bikes can be found with 60 – 120 km range and 50 – 110 km/h speed. charge time about 2 hours. the larger street/dirtbike tires are nice. https://www.ebay.ca/itm/450W-Electric-Bike-Left-Drive-Conversion-Kit-Can-Fit-Most-Of-Common-Bicycle/263783541634 https://www.ebay.ca/itm/450W-Electric-Bike-Left-Drive-Conversion-Kit-Can-Fit-Most-Of-Common-Bicycle/264822874262
