https://electricbikereview.com/pesu/monster-250w/ The PESU Monster 250W is a value-priced hardtail cross country style electric bike with adjustable SR Suntour suspension fork, versatile 650b wheel size, and mid-level Shimano Acera 9-speed derailleur, three frame sizes. Compact mid-motor from TTIUM is powerful, moderately responsive, and very quiet, assisting up to ~18 mph and offering up to 99 Nm of peak torque making it a capable climber. Larger than average Lithium-ion battery pack extends range and mounts to the downtube from the side so the top tube can be lower, making the bike easier to mount, USB charging ports. No rack, kickstand, or bottle cage bosses, only available online with a very limited warranty, crowd funded so delivery date is questionable, shipping costs $99 to $399 extra depending on location.
