How powerful is the Hill Topper? Will it work on my hill?
The Hill Topper utilizes a powerful 250 Watt motor. What does that mean? Well, it is like having another fit bicycle rider helping you pedal, but without their weight. No matter how hard your hills, or heavy your bike is, this motor will always work to help you get where you need to go without becoming fatigued. Just as long as you continue to pedal, the Hill Topper motor will help you top even the toughest of hills or your long ride to work. You get the advantage of another bicycle rider, but with less spandex and sweat! 

Grip Switch v.s. Twist Throttle. Can I control my speed with the on/off grip switch?
Yes, you can quite easily. Our kit is designed with simplicity, practicality and cost in mind. After research into how people use products that have a throttle we found that a large percent use them either on or off therefor we choose this a much easier to install push button grip switch. Your handlebars and brakes are unique and tuned perfectly to your riding style. Other electric bike conversion kits require you to completely replace and re-adjust your brake cable and handle grip system in order to operate their features.

Be careful not to bite off more of an installation project than you can chew. You may be disappointed with how difficult other electric bike kits are to work with. Also remember, many bike shops will charge top-dollar for their labor (maybe a half-day) if you ask them to install a complex kit for you. Keep in mind a bike shop worker or handy friend could install this Clean Republic electric bike kit in just minutes (probably a $25 labor cost), but may even refuse to install a complex one.

There's a good reason you don't see videos of competing electric bike kits being fully installed in minutes in real time with no editing.


Will the Hill Topper fit my bike?
Yes! The Hill Topper was designed to fit 95% of bicycles and adult tricycles on the road today. You can double check two things to be sure. 

First, we will need your wheel size. This can be found printed on the side of your tire. 

This is a 26in wheel
A 26 inch wheel

Secondly, the Hill Topper motor will need to fit in your bicycle fork (the two metal pieces that attach the front wheel to the bicycle). You will need at least 3.9 inches (100mm), about the same size as the long end of a business card, between the forks blades at the dropouts (where the wheel axle connects to the bike). Nearly all bikes have enough room for the Hill Topper motor to fit in between the fork blades.
