this bike came really fast. Very surprised at the quality considering the price. It was packaged very well however my fenders had a little kink in it during shipping. I don’t care about that. It is very fast and a solid bike. I own two other Nami electric folding bikes and this is on par with their quality. The only concerns I have is whether or not I’m able to purchase a second battery when this one needs replacement. This is my first electric bike and I’m very impressed with the fun factor.
The two most common types of hub motors used in electric bicycles are brushed and brushless. Many configurations are available, varying in cost and complexity; direct-drive and geared motor units are both used. An electric power-assist system may be added to almost any pedal cycle using chain drive, belt drive, hub motors or friction drive. BLDC hub motors are a common modern design. The motor is built into the wheel hub itself, and the stator fixed solidly to the axle, and the magnets attached to and rotating with the wheel. The bicycle wheel hub is the motor. The power levels of motors used are influenced by available legal categories and are often, but not always limited to under 750 watts.

While we're still fairly new to the solar ebike game, Mark is among the (suprisingly numerous) Grin customers who've been thinking about and experimenting with solar bikes for many years. After he shared pictures of his latest project and mentioned his round the world touring ambitions, we thought we had to do a small feature on this guy. A quick last minute trip to Maker Faire was arranged to meet up, and here we present, Mark Havran:
We need to support and put our purchasing power behind ebikes sold in the U.S. that are trying to comply with the California rules which allow 500w and 750w nominal motors and establish 3 classes. If these bikes can create a big enough footprint in the market then future U.S. bike rules may universally adopt these standards. It is better than engaging in regulation showdowns without any standardized and unified proposal on the part of the Electric Bike Community.

The Motan M-150 electric bike is one of the Addmotor’s best selling models. Featuring a 750W high-speed brushless rear hub motor, goes to the top speed of about 25mph.

Collapsible top-tube, frame, and pedals make it portable and easy to store in your car, and unfold in only 10 seconds when you’re ready to use it.


The federal Consumer Product Safety Act defines a "low speed electric bicycle" as a two or three wheeled vehicle with fully operable pedals, a top speed when powered solely by the motor under 20 mph (32 km/h) and an electric motor that produces less than 750 W (1.01 hp). The Act authorizes the Consumer Product Safety Commission to protect people who ride low-speed electric vehicles by issuing necessary safety regulations.[63] The rules for e-bikes on public roads, sidewalks, and pathways are under state jurisdiction, and vary.
