-There is also the option of the “Pro Pack” which is the Hill Topper without the complete wheel.  These Pro Packs are generally $100 less than the Hill Topper kit.  They are intended for bike shops or DIYers who want to build the motor into their own wheel.

The kit I tested came with the Axle Release quick release option.

Clean Republic has a very detailed frequently asked questions page.  They have answers to almost any possible question!

Installing the Clean Republic Hill Topper electric bike kit:

One of the unique feature of this electric bike kit is how easy it is to install (or uninstall) on your bike.  Here is a video that shows the basics:

IMPORTANT NOTE:  You need to check with Clean Republic to make sure the fork on your bike will work with their kit.  Here is a link to the FAQ page where you can find more info on this.

Once the Hill Topper kit arrived I installed it on the “Fixie” style bike from Critical Cycles that I have been testing for review on Commute by Bike.  Here is the video of my experience installing the Hill Topper:

Overall the installation experience was pretty smooth.  I had to move a spacer from one side of the hub to the other to get the motor to fit in the fork.  If you have a similar situation make sure you contact Clean Republic for the proper way to do this.

 

 

 

There is a motor wire connector that makes it very easy to install or remove the wheel from the bike.

 

Included in the Hill Topper kit was the Axle Release levers.  These are quick release levers that can be added to a traditional threaded axle.  They replace the typical axle nuts and allow you to remove the wheel without tools.  They work well on the Hill Topper kit because the motor wire comes out of the side of the hub, not through the end of the axle (some hub motors are that way).  They installed easily on the Hill Topper and they worked well to secure the wheel and release it quickly.

 

The kit is controlled by a simple on/off switch that is attached with a velcro strap to the handlebar grip.  I positioned the on/off button under the grip so that I could use my index finger to turn the kit on while still maintaining a secure grip on the handlebars.

 

 

 

When charging the lead acid battery pack you need to make sure that the on/off switch on the battery is in the “on” position.  In case you don’t know the “I” is on and the “O” is off.

 

Plugging in the charger requires that you disconnect the battery from the bike wiring and plug in the charger.

 

The charger is pretty small and light!  You can easily take it with you for charging on the go.
