Equipped with an aluminum hydro formed frame and a chromoly oversized fork, this wonderful bike offers pure strength that can provide support to all riders from the average sized to heavier ones, up to 400 pounds!

You will love the non-slip tread of its pedal made of resin platform. It also has durable, all-purpose, flat-resistant tires made with 26 x 2.3″ Kenda Kiniption, and with high tread count, so you will avoid the hustle of stopping at the shoulder of the road to make some repairs. The spokes are manufactured from a professional quality stainless steel; the rims are extra wide made of double wall  alloy; and the optional matching fenders will absolutely add style and design to this beauty.

Comfort is another thing that this e-bike offers. The handlebars are designed to position the rider in a more upright position that doesn’t strain your arms, back, wrists and neck while pedaling and steering. Mounted to the left side of the handlebar is the control panel which uses basic LED lights to approximate the remaining battery capacity and list the drive mode along with the assist level and light status. It also has a cushioned saddle ensuring that you will have a comfortable and awesome ride no matter how long it  will be. With these user-friendly features, this two-wheeled wonder can serve a number of users who either want a comfortable cruiser for a casual ride around the neighborhood or a stylish commuter to enhance efficiency of getting to work without being sweaty.

The motor driving this amazing electric bicycle has a 500 watt geared hub design that’s integrated into the rear wheel offering an excellent balance of size, weight, and power. And one of the coolest parts of this motor is how it’s mounted to the frame with a quick-disconnect for the power cable making changing flats easier.

This state-of-the-art electric bike is not just designed for comfort, style and durability but also considers ease, safety, and security of users as well as the unit itself. It has a battery that mounts to the bike frame in a unique way (actually sliding into an oversized seat tube) which conceals and protects it from external damage. Also, the battery can be charged on or off the bike so you can use the bike for commuting. You can just take the battery off and then charge it in the office. The brake levers are also set up to signal the motor when you are activating them and then cut power for safety and the shifters are standard triggers mounted to the right bar. Its top-of-the line braking system will give you good stopping power wherever you may be. It also has an impressive 7-speed gear system and three levels of assist thus, making riding a breeze!
