The Propella 9S PRO Review is an efficient, relatively light weight and well-balanced electric bicycle. There’s enough space for gravel tires, fenders, and mounting points to add a rear rack and folding lock. Clean aesthetic with internally routed cables and blacked out hardware. Custom battery pack uses premium 21700 Samsung cells, comes with an excellent three amp fast charger. Offers a unique blend of urban efficiency with good comfort. The higher volume 27.5" x 2.0" tires, raised stem, riser style handlebar, custom saddle, and locking ergonomic grips offset the harshness of a rigid aluminum alloy frame and fork. Optional suspension seat post further smooths the ride. Upgraded 12mm thru-axle in the front improves strength and handling. Powerful 350 watt internally geared hub motor sets this Propella apart from the 250 watt motor used on other models. It operates smoothly, is fairly quiet, and felt responsive thanks to a sealed high-resolution cadence sensor. Powerful 160mm hydraulic disc brakes with motor inhibiting reach adjustable levers. Fun to ride unpowered due to low weight and efficiency. Sold direct online with a bit of assembly required (front wheel, handlebar, saddle, pedals). Only available in one color scheme, one frame size, and high-step frame style to keep the price low. Key port for the battery pack is positioned very close to the left crank arm, but the charging port is up high. Shipping is $50 extra for the contiguous US and $100 for Canada.
