self propelled bikes

When you need more than 24 volts

 
 
 
 
 

As the price of gas continues it’s upward trend so does the interest in power assisted vehicles. Power assist enthusiasts are typically interested in simple human-scaled transportation that is earth-friendly, fun, non-intimidating, and affordable. Transportation that either extends the range of their bicycling, allows them to arrive at work without needing a shower, or allows them to leave the car at home more often. To that end I would like to talk about a product today that fills that niche perfectly..

 

 

The Hill Topper electric bike kits are among the best of the kits out there today in their respective power range & here are just a few of the reasons.


  • The Clean Republic engineers & other company representatives travel internationally to meet with producers and engineers to find the best motors, batteries, and electronics.
  • Hill Topper kits are assembled and quality checked in the USA along with other locally manufactured components.
  • Clean Republic has a 100% commitment & focus to their Customers & to their products. They are not being side tracked with building & or distributing other types of unrelated equipment.

Bigger is not always better.

  • Hill Topper hub motors are a 250 watt planetary DC brushless type motor, weighing just six pounds with a freewheel bearing design allowing for a zero drag when the power is not applied. Couple this to the additional weight savings you get from a 24 volt system & you have one of the smallest & lightest systems on the market today. Not to mention one of the simplest. Yet the Hill Topper still has a 15 mph top speed when running a standard wheel size.
  • The light weight & the simple design are not only a benefit to the rider who after all is still riding a bicycle but it contributes to making it one of the easiest units to assemble.
  • Finally this light weight & simple design make it a very flexible unit. After all a lot of us aren’t content to just electrify our stock bicycle & call it quits.

A final thought before moving to the details of the Hill Topper. Bigger is not always better because bigger is also heavier. The motor will weigh more & when you jump to higher voltage motors you’ll also need to add more batteries. It is primarily this weight that makes your bike feel less bike like. Not only are Hill Topper electric bike kits among the best they are also among the few available in 24 volt. Everyone makes & sells 36 volt & 48 volt kits but 24 volt kits are much harder to find.

  • The Hill Topper @24 volts & 250 watts is in the smallest class of hub motors. From here we move to the 400 to 500 watt motor.
  • Next move up the ladder is the 600 to 750 watt size hub motor.
  • Finally the top rung of that ladder is the 1000 watt hub motor.

Although you might find a 24 volt motor in something higher than 250w usually your next jump in both wattage & voltage is to add batteries & move up to a 36v, 48v, or even 72v. With a 24v Hill Topper Kit your bike will retain almost all of its original characteristics. The bigger you go the less bike feel. I tell you this because I’ve talked to many people that bought e bike kits & never even considered the weight & the size of the battery pack. Try jumping a curb with an additional 50lbs strapped to your bike. However, If you weigh 250 lbs & want to commute 8 hilly miles to your bank job in a suit & tie without breaking a sweat you might just need something a little bigger. See E-BikeKit.com for 36 & 48 volt kits else where on this page.

Where can you buy it & for how much?

In my travels around the internet I have seen The Hill Topper electric bike kits being sold by a number of Web Sites. Some of these sites where better than others to be sure. I suspect that most of them link back to a very small selection of retailers, Clear Republic themselves or a fulfilment center like Amazon.com. Prices range from $795.00 to $825.00 for the Hill Topper with the Lithium Battery Option & $399.00 to $440.00 for the Hill Topper with the SLA Battery Option. Freight will run $20.00 to $30.00 for either one. The only other cost is the optional 3-year extended warranty for $29.00.

I suspect that when the dust settles the final price difference is going to be pretty small. Amazon.com usually offers the most payment options & sometimes has extended terms as well. I included the links for the Hill Topper Electric Bicycle Conversion Kits @ amazon.com below. To check the prices at some other places just copy and paste Hill Topper Electric Bicycle into your search engine & check around. Regardless of where you buy your Hill Topper Clear Republic stands behind their product. You just won’t find a more customer service oriented company.
