My first e-bike had LEAD ACID cells for the battery pack, weighing near to 30 kilos. Was a work out just getting the bike moving. As for stopping, the brakes were completely inadequate (useless). Praise the Lord for lithium cells.
Did you ever encounter this term called "motorbike"?
There is an arms race amongst the electric bicycle manufacturers: More Amp Hours in the battery, more kilowatts in the over sized motor drum, central drive, prop shaft drive, bomb proof welded spider frame, and so on. Reality, most e-bikes are NOT electric bicycles but electric motorcycles with added pedals.
These $3000+ e-bikes are being sold with "pedal conversion" kits. Simply, manufacturers are adding cheap and nasty plastic pedals and chains for
regulatory compliance. If it has a 2500W motor, a 100Ah battery, a top speed of 80mph and, it has
pedals, then it must be a bicycle. Right? Which means no road taxation, no vehicle insurance and no vehicle testing to stamp the
pink slip every year. Plus, your five year old son can legally ride it on the highway and all pedestrian footpaths. Pedal kits can be removed and replaced with foot rests - which the supplier conveniently sells on their Chinese website. Unfortunately, fitting footrests also requires the fitment of road legal mirrors, indicators, a speedometer and let us not forget, efficient brakes. Because your five year old son might just need to go from 50mph to zero when he encounters a red traffic signal. Newsflash:
Electric motorbikes must stop at red traffic signals, whereas electric bicycles (and manual bicycles) never have/ever will.
Compare and contrast that barbecue on spokes with this 'budget' electric motorcycle:
