    Purchased this bike for myself and my wife was so envious I got her one, too. One word of warning – don’t take the corners too fast!

Mag Wheels for Boomerang Plus:

The Pedego Boomerang is the most accessible electric bicycle ever, making riding more fun and easy for everyone.

The number one thing this e-bike boasts is convenience. Its super low 9″ step through frame will allow you to access the bike with ease. This feature is perfect for those who cycle in dresses or who have a challenging time getting on and off a bicycle. Its seven-speed gearing system will provide you with the finest acceleration and easy pedaling, and allow you to climb hills more efficiently, without draining all your energy. You will love its 500-watt brushless geared rear hub motor with five levels of pedal assist that lets you ride effortlessly. You can simply turn the motor on and let this two-wheeled wonder do all the work for you or use it with pedaling so you won’t exhaust the battery and at the same time get some exercise. All of these awesome features and components will give you a convenient and therefore an enjoyable ride every time!

Strength and durability is another huge thing this premium quality electric bike offers. It can support all riders of all shapes and sizes, up to 350-pounds. If you choose the Mag Wheels option, the weight capacity goes up to 500-pounds. You will be amazed with the robustness of the frame made with aircraft-grade aluminum, the 3-piece alloy crank, suspension seat post, sealed bottom bracket, and other top-of-the line components that will give you a robust riding experience. You won’t have to worry about broken spokes or cranks.

If you’re looking for a comfortable ride, you have it right here! The Boomerang Plus electric bicycle’s wide, deluxe saddle provides extra cushioning to dramatically decrease the chances of saddle sores. The wide, swept-back handlebars will allow you to ride in a position where you can sit back and relax, greatly minimizing hand, wrist, neck, and back strain from long rides; and the premium balloon tires give great traction and stability for a nice, smooth ride. The tires are Kevlar belted and the tubes are self-sealing to help prevent flats. You won’t have to worry about the hassle of fixing tires when you’re rushing to go to work, school, or running an errand.

If you think electric bikes are complicated to use, think again. The Boomerang Plus is absolutely user friendly. The twist-and-go throttle feature will deliver full power on demand and with just one twist. It has an LCD display that shows your ride time, speed, trip distance, battery power, and pedal assist level. It also has a USB charging port for your cell phone and other devices. It has a full coverage chain guard that protects your clothes and your legs from getting greasy chain marks.

Safety are another important thing the Boomerang Plus provides. It has front and rear lights to keep you visible to drivers, pedestrians, and other riders when riding at night or on a gloomy day. The high quality disc brakes offer powerful, reliable braking every time. These small but incredible parts will stop the bike on a dime whenever you need to. And if you’re looking for speed, this beautiful machine has it! Using just the battery power, you can enjoy riding up to 20 miles per hour!

Because your safety is as important to us as you’re having fun, we will only ship this cycle to a bicycle shop where they can assemble it for you and show you how to safely use it. If you do not have a shop in mind, please just let us know and we will find one in your area to assemble the bike for you. It’s another way Zize Bikes puts you first.

This cycle definitely has it all – strength, comfort, convenience, safety, style, and more! Should you have any questions about this custom, extra sturdy electric bicycle for heavy people.

This bicycle has all the incredible benefits of the Boomerang Plus, but its weight capacity is substantially higher. These Mag Wheels are maintenance free and incredibly strong. Riders up to 500 pounds will be safe and comfortable, and feel great knowing that they are riding such a stylish bike.
