Zoom up the hardest hills and turn heads as you show off your new super powers. The powerful and compact 350W motor provides a speed of 20+ mph at the push of a button and the pedal assist system provides a steady 15 mph cruising speed with each pedal stroke (throttle is optimized for speed, PAS is optimized for greatest battery range). New features this year include an easy to remove Hilltopper lithium battery with 25 to 50+ mile battery range, a battery lock, led battery gauge that tells you how much power you have left, disc brake compatible hub, a USB charging port for your phone, a thumb throttle that allows you to control how much power the motor gives you, an easy to install pedal sensor that gives you power with every pedal stroke, a lithium battery charger optimized to ensure a long battery, and a higher efficiency Hilltopper motor that gives more torque for energy used (this motor is more compact than the Sprinter and also 60% more powerful). This is the original Hilltopper “Go Fast Now” kit, updated for 2024. Fast, with only the features you need. Rugged, with the battery range for long days. Awesome!

Your wheel is customized to fit the wheel size of your bike. Stainless steel spokes are combined with a double wall rim. Nylon rim tape provides extra protection against flats. A complementary Kenda tire & tube is included to make installation easy (and save you money). The wheel is compatible with rim and disc brakes to give you as many options as possible.
At the center of things is a 36V Hilltopper 350 Watt Electric Motor in black. Small & compact with a high torque to size ratio, this motor provides a 20 mph top speed and higher with pedaling. Torque roughly doubles the average persons pedal power. Hilltopper motors are legendary for their long lifespan, typically outlasting your bike.
Motor is powered by a 36V 11.4 Ah Lithium Ion battery. Range of 25 - 40+ miles depending on how much you pedal and the terrain. Built in a rugged duraplastic case, this battery mounts on your downtube using the water bottle cage mounts. Or on a rear rack or in a basket. Battery has a LED gauge that tells you how much charge is left, plus a lock that keeps the battery safe and makes it easy to remove when you need to recharge. Very energy dense, with a lots of range for the battery size. The complete battery pack is 378(L) x 78(W) x 99(H) mm.
Activates your super powers and allows you to control how much assist the motor gives you. Fits most handlebars (hybrid, mountain, cruiser, etc.). For drop bars (found on road bikes) please see FAQ for fit. Installs by sliding on, you must remove your grips first to install. Very easy to use and long lasting.
Charges your 36V battery in 4-5 hours. Optimized for Lithium-Ion chemistry, this charger ensures a long lifespan for your battery.

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.

For information on storing you battery, please hop over to FAQ When Should I Charge My Battery?
You can charge your Hilltopper whenever you like! All of our batteries are smart batteries with no memory affect, so there is no need to drain it fully before recharging like you would with older battery types like NiCad or others.
Generally we suggest simply charging it after every ride, or at the end of the day if you are a regular commuter. That way you always know your battery is ready to go when you are.
If you are putting the bike away for the winter or just know you won't use it for some time, we suggest charging it fully first and storing it in doors. For the absolute best life of your battery we would also suggest plugging it back into the charger every month or so to keep it topped up. Before you ask, no, unfortunately we cannot suggest simply leaving the battery plugged into the charger long term.
For all of our electric bikes and conversion kits we've made sure charging is easy as can be. Just a few simple steps:
That's it! Follow these steps and you can rest assured you'll be ready to roll!
36V 2020 Sprinter battery has 10 - 20+ miles of range.
36V Universal Battery Replacement has 20 - 25+ miles of range.
36V 2020 Horizon battery has 25 - 50+ miles of range.
48V Summit battery has 25 - 40+ miles of range.
Mileage rates are based on a 170 pound rider on a 30 pound bike on a flat paved surface, with no wind, using the motor and not pedaling. Your mileage may vary, though most people get more than advertised mileage. For the best possible mileage we suggest pedaling anytime the motor is engaged.

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.
