Overview
The Geleisen PM-09 is a 20 inch fat-tire folding electric bike with a 350W motor (500W peak), a 374.4Wh battery rated near 25 miles on pedal-assist, and a steel cargo rack rated to 300 lbs. It suits riders around 5'0" and up who want a compact commuter or beach cruiser that folds for storage.
- UL 2849 safety certification for bike and battery
- 3 riding modes: electric, pedal-assist, standard
- Multifunction LCD shows speed, battery and mileage
- Arrives about 85% assembled with included tools
Who it's for
Suits casual riders, commuters and beach or park cruisers who want a folding e-bike under $500 and can tolerate variable build quality. Less suited to anyone who plans to fold and unfold the bike often, given at least one report of a wiring fault during folding, or riders who need the full advertised 25-mile range.
What buyers say
From Amazon customer reviews.
Most buyers describe the ride as smooth, stable and good value for a sub-$500 e-bike, with the folding design and steel cargo rack getting repeated praise for storage and grocery runs. One reviewer reported a serious fault: folding the bike disconnected the internal wiring, and unfolding it caused a spark that shorted the bike out after only two rides. Others noted the handlebars need tightening and retightening after setup, and that real-world range can run below the advertised 25 miles.
Strengths and trade-offs
Drawn from this product's published specifications.
- Folds compact enough for an SUV or apartment storage
- Steel cargo rack handles groceries and gear
- Most riders finished assembly in 30 to 40 minutes
Performance notes
A 350W rear motor (500W peak) drives the bike through 3 modes, pure electric, pedal-assist and standard pedaling, with 6-speed gearing to adjust effort by hand. The 374.4Wh battery is rated near 25 miles on pedal-assist and about 15.5 miles on pure electric, though real-world range varies with rider weight, terrain and assist level, and at least one reviewer saw closer to 15 miles overall. The fat 20x3.0 inch tires and dual disc brakes are built for mixed pavement, sand and light trail riding rather than speed.
