Built by hand at our shop in the Sodo neighborhood of Seattle. Your wheel is built to order and customized to fit the wheel size of your bike. Stainless steel spokes are combined with a double wall rim. Cloth rim tape provides extra protection against flats. A complementary Kenda tire & tube is included to make installation easy (and save you money).
At the center of things is a Bafang 250 Watt Electric Motor in silver. Small & compact with a high torque to size ratio, this motor provides a 16 mph top speed (pedaling required). Torque roughly doubles the average persons pedal power. Bafang motors are legendary for their long lifespan, typically outlasting your bike.
Motor is powered by a 36V 6.6 Ah Lithium Ion battery. Range of 20+ miles depending on how much you pedal and the terrain. Built in a rugged and waterproof neoprene case, this battery mounts anywhere on your bike using the quick to attach velcro straps. On the top tube, your seatpost, on a rear rack or in a basket. Battery. One of our most versatile batteries, this battery fits any bike, oddball, or oddity.
Activates your super powers and allows you to control how much assist the motor gives you. Fits all handlebars (road, mountain, cruiser, etc.). Installs by sliding on, you must remove your grips first to install. Very easy to use and long lasting.

Why are Hilltopper Bikes 1/2 the price of other e-bikes on the market? Because we sell direct to you, the customer. Our mission is to create a sustainable future, two wheels at a time and we do that by making e-bikes affordable for you. We intentionally don't sell through dealers, distributors, or retailers because that way of selling means a higher price tag for you. We build our kits and bike wheels with love and care here in Seattle and sell direct to you, so you won't see the large retail markup that would be present if you were buying from a third party. That way you're always getting the best deal on your electric bike.
It depends on how fast you want to go, and how steep the hill.
The 36v, 350 watt kits and bikes can go 20 mph with minimal pedaling. This is the legal limit in most of the US for e-bikes so it's enough power for most bikes. This is a great power for steeper hills, faster commutes & carrying bigger loads. It's like having two Soul Cycle instructors also pedaling for you.
The 36v, 250 watt Sprinter kit can go 16 mph with minimal pedaling on flat ground, but they perform best as a boost to your pedaling with pedaling required on hills. Perfect if you are looking for an added boost to your ride at an affordable price. Cuts your commute time by 25%, flattens out that hill by 50% & puts a smile on your face.
The 48v, 750 watt Summit kit can go 20 mph with minimal pedaling. This is the legal limit in most of the US for e-bikes. The motor could go faster, but it is limited at 20 mph for safety and to remain street legal in the US (unlimited it could go 30+ mph). The 750 watt motor can carry large loads up steep hills and accelerates quickly. Perfect if you are looking to cruise consistently at 20 mph over varied terrain or climb absurdly steep and long hills while hauling groceries. It's more power then you might need. But its a lot of fun and gives you the piece of mind that you can accelerate out of any sticky situation.
All Hilltopper electric bikes and kits have a maximum speed of 20 mph. This keeps them street legal and compliant with state laws and city ordinances in the US.
For choosing a power system, here's what to keep in mind:
The 36v, 350 watt kits (Horizon) can go 20 mph with minimal pedaling. This is great for steeper hills, faster commutes & carrying bigger loads.
The 36v, 250 watt kits (Sprinter) can go 15 mph with minimal pedaling on flat ground, but they perform best as a boost to your pedaling with pedaling required on hills. Perfect if you are looking for an added boost to your ride at an affordable price. Cuts your commute time by 25%, gives a boost up hills & puts a smile on your face.
There are many different types of bicycles and adult tricycles in the world today, but each Hilltopper conversion kit has been carefully designed to fit as many of these models as possible. All Hilltopper wheels are designed to be compatible with both rim brakes and disc brakes.
There are a few more factors used to confirm that the Hilltopper will fit your bike. 1) Wheel Size. 2) Hub and Fork spacing. 3) Fork Dropout Type. See FAQ Will It Fit My Bike? for more information.

Our variable speed throttle is just one piece of our kits that allows the rider to control the amount of power fed to the motor - kind of like a gas pedal!
The throttle is a versatile piece that can be installed on your handlebars and adjusted to whatever suits you and your bicycle best. We recommend putting the throttle on the left, placing them between the handlebar grip and the brake/shifter levers.
The most common type of handlebars on the market today would be a flat or riser handlebar. Our throttle is specifically made to match these handlebars with its 22.2mm grip diameter.
While the throttle grip is too small to fit most road bikes, drop bars, and any other handlebars with uncommon geometries, there is a pretty simple workaround - a handle bob (a quick Google search should get you plenty of result) can be attached to any of these handlebars for a quick and easy install.
Check out our video on how to install the variable speed throttle!
All HillTopper kits come complete with a tire already installed so you can get going quickly. That said, our awesome tires might not be the best fit for you bike or your style.
No problem, swapping out the tire to meet your needs or match your other wheel is super easy. Our rims can fit a wide variety of tires, everything from skinny road tires(25 mm minimum) to big 2.2" mountain tires.
For instructions check out the following video:
Yes, all Hilltopper wheels are disc brake compatible with standard spacing and 6-bolt rotor attachment.

There are many different types of bicycles and adult tricycles in the world today, but each Hilltopper conversion kit has been carefully designed to fit as many of these models as possible. All Hilltopper wheels are designed to be compatible with both rim brakes and disc brakes.
There are a few more factors used to confirm that the Hilltopper will fit your bike. 1) Wheel Size. 2) Hub and Fork spacing. 3) Fork Dropout Type. See FAQ Will It Fit My Bike? for more information.
The type of drop out your bike has is very important. The dropout is the place at the end of your fork where the wheel attaches to the rest of the bike.
For the longest time there was really only one type available; the "open" or "slotted" type. This is the familiar U shape you have likely seen on most every bike you can remember. Your bike must have this type for our electric bike conversion kits to fit. All conversion kit axles have a width of 10mm.
Another type of dropout that is found on a small number of high-end bikes is the "closed" dropout. This is for use only with "thru-axle" hubs, and our e-bike motors are unfortunately not compatible.
Our hubs have a 100 mm(or about 3.9 inches) axle, which is standard for most bikes. To confirm that our electric bike hub will fit into the fork on your bike we need to check the spacing of "the fork." The fork is the two metal arms that hold either side of your front wheel. If there is about 3.9" (100mm) the Hill Topper should fit great!
Since our electric bike motors tend to be a bit taller than the average bike hub, there is another fork spacing consideration to look for. Most bike hubs are only about 2-3" in diameter, but an e-bike motor can be up to 7" tall. As such, we need to ensure that the 4" spacing mentioned above does not diminish too quickly above the dropout. For the best possible fit, that 100mm/4" spacing should be maintained at least 3" above the dropout.
If you find your measurements fall within the “Maybe” category, the best way to find out if it fits is to simply try and install! Thankfully we offer free and easy returns, so if it doesn’t work out, you can always return the kit! See our “Warranty, Returns & Shipping” section for more details.
We offer all of the most common wheel sizes on the market today, including; 700c/29", 27.5", 26", 24", and 20" wheels.
You can find your wheel size printed on the side of the tire on your existing wheel.
Please note:
I now have three of these kits. We have a house in Vermont and a condo in Florida. Rather than schlepping the bikes back and forth we keep bikes at both ends. The kits in Vermont are considerably more useful, as the pitcher’s mound on the Little League field is the highest mountain in Florida, however we are on the coast so we get a bit of wind. Just installed the first kit in Florida (there will be a second for my wife) and actually got more of a workout than I normally do. I just put the bike into the highest gear, so I’m working hard even on the flat. When I get really pooped I just pop the magic button for a couple of seconds, which gives me a short break – and then it’s right back to top gear, 2 gears higher than I normally use. These kits are perfect for my needs; don’t want an “electric bike,” just want a little boost once in a while. Well made, trivial to install, and we did schlep the batteries from Vermont to Florida, so the cost was quite reasonable. We have the 20 mile batteries, but since we pedal all the time we’ve never even come close to using them up, even after distances well in excess of 20 miles.
