The 250w
EBikeBC is $1,000 and weighs just 25lb which is light for an ebike. Court Rye did a video review of the identical but more expensive
VeloMini Plus. It has smaller 16" wheels and the back wheel folds under the frame which has a carrying handle, the small 240wh battery is inside the frame so it looks like a normal folding bike, it is a single speed, has a throttle and pedal assist but is geared high and this
owners review recommended starting off using the twist throttle then pedalling. Top speed is 14mph, and range is 8 miles on throttle only up to 18 miles pedalling all the time in the lowest level of pedal assist so maybe 10-12 miles combined - battery range is an issue on folding ebikes because of the trade-off between small size batteries to keep weight down, for comparison the
BH EasyGo Volt is a 20" normal looking folder with an even smaller battery delivering similar speed/range to the EBikeBC but weighing 39lb. My wife test rode the Tern Vektron last weekend and she liked the adjustable handlebar stem that adjusts for rake, bar angle, and height.
