Equipped with 350W high speed brushless motor, providing more than enough to power your daily commute, a cruise on the mountain, or a meander along your favorite trail. With speeds up to 22 mph, it will get you there swiftly.
With the 48V 10.4Ah Lithium-Ion battery, you can reach a range of up to 80 miles per charge without I-PAS. Plenty for a day’s adventure or most trips to travel and back. You can charge the battery on/off the ebike by your convenience. No worry for being stolen.
With these front and rear mechanical 160mm disc brakers, you can stop the bike in a more effective way, even in loose terrain. Stop faster when it counts the most. The mechanical disc brakers are currently the more popular type of disc brake for the average mountain biker. One of the main perks of the mechanical disc brake is that the cables are far easier to install and they work more efficiently.
The Aluminum Alloy frame– light, strong and designed to last, makes it easy to maneuver. Aluminum Alloy double-walled rims are for greater durability as well as faster ride with less drag. A high- strength front suspension fork can take your riding comfort to the next level.
The 7 speed, 14-28 free wheel means you can shift to a larger cog for uphill riding, downshift to a smaller cog at high speeds. This greatly increases the comfortable performance of the bike on hilly terrain. Multiple geared bikes also require replacement gears less often, because abrasion is distributed among multiple chainrings rather than a single chainring.
With 10W LED light, Challenger allows you see further while riding. More protection, extra safety.
Now you can upgrade your Yamee to have a cruise control feature.
