Components

  • 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.

  • Charges your 36V battery in 3-4 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.

Range of the Battery and Speed

  • 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.

  • For all of our electric bikes and conversion kits we've made sure charging is easy as can be. Just a few simple steps:

    1. Grab the charger supplied with your Hill Topper and plug it into the wall. For the best possible performance we recommend plugging directly into the wall, avoiding the use of extension cords and power strips whenever possible.
    2. Once the green light on the charger comes on, go ahead and plug the barrel end into the battery.
    3. When the charger is connected to the battery the light should turn from green to red to indicate that it is filling up the battery.
    4. As soon as the battery is full the light will turn back to green so you know it's done.

    That's it! Follow these steps and you can rest assured you'll be ready to roll!

  • 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.

  • 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.

    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:

    • We carry 700c/28"/29"(all the same rim diameter - 622mm), 27.5", 26", 24" and 20" wheels.
    • We do not carry 27".
    • No custom options are available at this time.

I had one hilltopper for a few years on my wife’s bike , and it worked out well for her and she loves it. Since i ride more then her i decided to bay a hilltopper for my bike and we were sharing the battery. also worked out well if we both went she would use and i would just ride without. Finely the battery wore out . So we ordered a new battery ,we had some connection issues between the old cables and the new battery , But thes customer service techs are Great they worked with me to get things working and replaced the new battery and cable , and got me working ,couldn’t be happier. I just need to get one more cable so we can share the battery again. Thanks for a Great product. Dennis Cray. Kinston NC

I have had kit since 2013, ride on hilly terrain 6 to 15 miles about 14 days a month (except during months of November – March), I just love it! In my experience, You can’t beat the price, quality or customer support. I did end up getting a steel fork as they recommend- there is enough torque on the 250 W motor to bend an aluminum fork.

Earnest Harn

Great kit, no regrets here 🙂

I was in a time line when I ordered the front wheel for my wife’s bike, Hilltoppers came through with flying colors getting my order out the same day and two days later it was delivered. Larry

This may be a bit lengthy but I want to give people some info that may help them. I’m 6’9″ and weigh 260 lbs., my Specialized bike weighs 60 lbs. with the Commuter kit installed, 250 watt.,so I’m asking a lot from it. It has performed better than I thought it would carting this big load around. I haven’t taken it on any long rides yet, just 4 or 5 mile runs with some good inclines. With me pedaling, it has gotten me to the top with no issues. On the flat I can reach 15 mph quickly with me assisting. I will have to update my review when I see how long the battery lasts after I hit the trails. The install went perfect, no filing anything. At this point in time I’m pleased with the Hilltopper, hope this helps. ‘Update’ Went on a 37 mile ride today and the Hilltopper performed great, when I needed a little help I hit the button and all was well. I still had battery power left after finishing my ride, I only used it when I was pedaling and it was one of my most enjoyable rides. I wish I knew about this kit a year ago…

I got my Commuter Electric Bike Kit Monday and installed it on Wednesday. It took approximately 30 minutes to complete the installation. Very easy to do. I took it for my first ride yesterday in Sequim. We rode west on the Olympic Discovery Trail. A perfect day to test it out…the wind was blowing out of the west at about 25 mph! The kit worked perfectly! It made battling the wind a breeze and greatly assisted climbing several long hills without any problems! We came upon a radar speed check road sign and I registered 19 mph which I thought was really good seeing I weigh 220 lbs. I love the kit and will highly recommend it to anyone looking for an electric bike kit!

Adam

I love my Hill Topper. My Hill Topper has completely transformed how I get around in Seattle. Besides the very occasional bus ride, my Hill Topper-enhanced bike is now all I need to get around town on a daily basis. I probably put 20 or so miles on my bike a week pre-Hill Topper, but now I ride at least 60 to 70 a week. Having the Hill Topper essentialy flattens out some of the intense hills here in Seattle, and I can’t overstate how that has resulted in a paradigm shift in the way I use my bike. In short, I sing the Hill Topper’s praises to anyone who will listen.

Randy Mealer (Defiance, OH)

I bought a 20″ front for my burley and I think this is the greatest thing out there for a 70yr. old. It is exactly what I needed to keep riding long and far. Helps with start ups at stop signs and up the hills. No more serpentine all over the road when climbing with traffic all around. Thanks for for this wonderful product.!

LivingLight (The Villages, FL) 

Wow, my kit is still working great. I do a review every year to let people know how my 700c 24v 250w 20-mile Kit is working. So far there are zero problems. Living in Florida…heat, Rain and perfect weather…doesn’t matter….works perfectly. Sooooo Happy! If you decide to make a purchase…get a discount using my code: livinglight You won’t be sorry.
