https://electricbikereview.com/rad-power-bikes/radexpand-5/ The Rad Power Bikes RadExpand 5 is an affordable folding electric bike with powerful geared hub motor, high capacity 48 volt battery pack, integrated lights with bright braking activation, custom plastic fenders, and a sturdy rear rack all included! Optional front tray, baskets, panniers, suspension seat post, child seat, mobile delivery service, and more. Sturdy reinforced step-thru frame is approachable, offers a highly adjustable handlebar, and is available in two colors: black or white. Reflective tires enhance the visual footprint, along with the side cutouts on the headlight, and a flick bell is included for signaling. Reliable braking with large 180mm mechanical disc brakes with motor inhibitors. High volume 4" wide fat tires provide stability, float on soft terrain, and comfort. Their knobby tread is capable off-road, and provides further vibration dampening. Ergonomic rubber grips, comfort saddle with handle, and large platform pedals feel secure. Great 7-speed drivetrain with chainring guide offers 14 to 32 tooth spread for starts and climbing, trigger shifters are easy to reach and actuate. Compared to older generation RadMini folding ebike products, this 5th generation bike does not have a suspension fork. This reduces the weight of the bike by ~6.5lbs, lowers the cost, and improves compliance. Folding joints felt very secure, large gussets limit frame flex and increase the weight capacity. Basic LED display readout lacks a USB charging port and does not communicate speed, but they do sell an optional upgrade to LCD display.
