The Original Hilltopper

This is the kit that started the electric bike revolution, updated for the 21st century.

  • 1.

    Seattle Born & Bred since 2008.

  • 2.

    Rugged & versatile kit for people who want a boost on their ride. For riders who want more power we recommend the Ranger, Horizon, or Summit.

  • 3.

    Performs best as added power to your pedaling. Great for people who love to ride bikes but want to flatten out the hills and cruise at a higher speed.

  • 4.

    Cuts your commute time by 25% and how much you pay for parking or Uber by 100%.

  • 5.

    Fits most bikes & adult trikes. Minimalist design gives hidden super powers appeal (folks can't tell its an e-bike).

  • 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.

Installation & Charging Instructions

  • The 2020 36 V Sprinter HillTopper electric bike conversion kit is a big step up from our original systems both in tech and performance. The higher voltage offers more power and efficiency while the bottle battery gives you a sleeker look, USB to charge your phone, plus a lock to keep your battery safe and secure.  On top of all that the new throttle offers a bit more control.

    Here are the basic steps you'll need to follow:

    1. Remove your bike's original front wheel.
    2. Install your new Electric Bike Wheel, being careful to ensure all of the axle hardware is in place.
    3. Affix the battery mount to your bike's water bottle mount or a rear carrier, then set the battery in place and lock it to secure it.
    4. Remove your your handle bar grip. (You can choose right-hand or left, it's totally up to you.)
    5. Install the throttle on the handle bars. (It can be position any way you like, push forward, pull back, right-hand or left. It's dealer's choice.)
    6. Use the thick black cable to connect the battery to the motor. (Make sure to align the arrows and you'll be all set, not need to worry about the little pins.)
    7. Use the thin cable with yellow plugs to connect the battery to the throttle.

    And that's it, easy!

  • 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 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:

    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!

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.

    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.

Will It Fit My Bike?

  • Yes, all Hilltopper wheels are disc brake compatible with standard spacing and 6-bolt rotor attachment.

    All of our wheels are also rim brake compatible giving you the most options to fit your bike!

     

    For instructions on how to install a rotor on your new Hilltopper, check out the following video:

    https://youtu.be/ZxDQUXOZqps

  • 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.

  • We offer all of the most common wheel sizes on the market today, including; 700c/29", 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), 26", 24" and 20" wheels.
    • We do not carry 27" or 27.5".
    • No custom options are available at this time.

165 reviews for Sprinter Electric Bike Kit
Matthew

I have been wavering between a 4 and 5 star review, and while there are still some issues with this kit, I still think the fair review is to round up to a 5. The bottom line is, it’s a great value, there is nothing else on the market like it at this price point, and if you’re on the fence, I’ve got to nudge you towards buying it. I’m very glad I did!

First, the problems: The instructions– and more importantly, the diagrams– still have not been updated to match the updated kit. Yes, you can figure it out, as others have noted, but I think the description of the washers on the axles just doesn’t quite match. This is a kit for a moving vehicle, there’s the potential for risk here, even if it’s remote.

Also, my bike shop recommended being sure to tighten the nuts way past finger tight– not pneumatic socket tight, but as wrench tight as possible– not sure the manual mentions this, consult your mechanic. I did have to have the front dropouts filed because they were too tight for the kit, an extra $50 that I was expecting. I installed the rest of the kit myself.

Most significant, for me, is that the screws on the battery housing/cage will NOT stay tight on my bike, no matter how hard I screw them in (however, read on– the terrain I’m using the bike on is a bit unusual.) I found a workaround with zip ties that keeps the housing secure and is virtually invisible, but for me, the screws still *must* be tightened after every ride. I bring a Phillips head screwdriver every time I go out, but in fact, it’s probably a good idea to bring a few basic tools on every ride no matter what bike you’re sitting on. Again, some risk here, even if it’s remote– I would not want the battery to fall off, drag, or foul in the chain somehow. Inspect after EVERY ride, and LISTEN for unfamiliar rattles when you’re out– that’s what tipped me off my second ride, when I very nearly lost the battery.

The connection between the battery and throttle is stiff, hard to connect, even harder to disconnect, and the arrows to align each side are very hard to see or feel. This is probably only an issue during installation– you dress the cables, and figure “Nah, I want to take this apart and run them differently” but it’s not that easy. I’d prefer a locking collar system, though I know stuff like that adds expense.

It is a little tricky working the throttle and also the shifters, but not nearly as bad as I feared– I do have some arthritis in my thumbs. I prefer the throttle on the right, but think it through for your own setup– this means I’m doing a lot with my right thumb, three levers to manage. On the left side, you’re shifting less if you have a front derailleur.

Now, the good– and there’s plenty of it: The battery actually will do 13 miles under fairly hellacious conditions– first 1,000 feet of vertical straight up, 500 down, 200 up, 600 down, 400 up, etc., including grades of 12% or more, using moderate throttle. This requires pedaling enough for a very good workout, but no burning legs or lungs, and the battery didn’t die until the end of the very last hill. The steepest grade it has managed so far is a truly gnarly 15% that is about three tenths of a mile– I was never able to do this hill under my own power, even in my early 40s. (I am 63, 6’2″ 145 pounds and fit, though I have a health condition.) The front wheel begins to lose traction over 12%, but it can be managed by leaning forward, and I think the kit could do 16% for a more skilled rider. That is really pretty impressive…. holy crap, guys, I can ride to places I never could before here in the Hollywood Hills.

My bike is a 30 pound Trek 930 that is heavily modified specifically for rippled, cracked and broken asphalt– with the kit, it is 41 pounds, very light for an e-bike at this price. I use the bike mainly for fitness and exploring Griffith park. So I’m experiencing more short-to-medium period vibration than most riders will, which could be part of the battery mount issues. I’ve got a late-’90s Girvin front stem suspension system and suspension seat post and a rear gear cluster with an oversized low gear. (The suspension does not impact vibration to the frame, would be the same without it, and I no longer use the super-low gear.) The kit is very well balanced, probably because the battery and motor are mounted relatively low, and the extra weight in the front hub may add some gyroscopic stability or something– it feels MORE stable in tight corners than it did before. Front wheel drive is cool when cornering– you can nudge the throttle to pull yourself through the end of a sharp curve a little bit, as you would in an FWD car. But be careful! Going UP 15% on a crazy hill I could never manage before often means I will be going DOWN the same hill, with all that rippled and cracked asphalt! Downhill speeds now are exceeding 30 MPH, though I’m holding back a bit until I get some work done on the brakes.

Sorry if that all was a little OCD! Anyway, it’s hard for me to stay in shape during the winter in SoCal, so this is really opening up a whole new world for me. With the caveats recommended above, I highly recommend the kit.
