Install it like this

Your old bike is your new bike!

Convert your old bike to an electric one in just a few minutes. It's easy, quick and fun. All you need is a Hilltopper kit and a friend to race when you're done!

Components

  • Your wheel is built by hand. Stainless steel spokes are combined with a double wall rim. Extra thick nylon rim tape provides extra protection against flats. A complementary Kenda tire & tube is included to make installation easy (and save you money). All wheels are disc brake and rim brake compatible.

  • At the center of things is a 48V 500 Watt Electric Motor in black. This high torque motor provides fast acceleration and a continuous 20 mph top speed to ensure your bike remains street legal. Hilltopper motors are legendary for their long lifespan, typically outlasting the battery and your bike.

  • Motor is powered by a 48V 10Ah Lithium Ion battery. Range of 25 - 50+ 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 turns it on and off. Very energy dense, with lots of range for the battery size.

  • Enjoy a boost every time you pedal. LCD display controls how much power the motor adds to your pedal stroke, while also providing real time data on your speed, battery usage, and miles traveled. Pedal sensor is two pieces, and easily clips on to your cranks. This is a full feature kit that can be installed at home without specialized tools.

  • Activates your super powers and allows you to control how much assist the motor gives you. Fits most handle bars (fits all flat bars, mountain, hybrid, cruisers, etc. may not fit some drop style road bars). Installs by sliding on, you must remove your grips first to install. Very easy to use and long lasting.

  • Charges your 48V 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.

Installation & Charging Instructions

  • The 2021+ 48 V Summit HillTopper electric bike conversion kit is our top tier kit. This kit offers the highest amount of power and miles. The downtube battery keeps a sleek look, it has USB to charge your phone, plus a lock to keep your battery safe and secure.  On top of all that we've added a new Pedal Assist Sensor and LCD screen as a bonus feature.

    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. Install the LCD screen and keypad on your handlebars. The LCD should be placed in the middle of our handlebars, with the keypad to the left of the screen.
    7. Use the thick black cable to connect the battery to the motor. (Make sure to align the arrows and you'll be all set, no need to worry about the little pins.)
    8. Use one of the thin cable with yellow plugs to connect the battery to the throttle.
    9. Connect the LCD screen to the battery using the black, 6 pin cable.
    10. This one is a bonus; for hands free pedal power, use the other thin cable with a yellow connector to plug in the PAS sensor. Use a zip-tie to attach it to your bike frame just behind the gears at your pedals.
    11. Take the magnet wheel and split it into it's two pieces, then reconnect them around the bottom bracket spindle between the gears and the sensor.

    And that's it, easy!

  • 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!

    These basic principles apply to all of our24V kits from 2019 and prior.

  • 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!

    Check out our video on how to charge your battery!

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.

  • 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.

After a failed installation of a FALCO kit I tried this SUMMIT kit and got it going sweetly in a couple hours… all I ever wanted for a DIY installation!

Excellent and well-engineered kit for converting a well-maintained 15 year old Specialized hybrid road bike! A couple things of note: Please add greater detail on operation of the LCD control panel. For example, no where in the instructions are details on navigating to the set-up screen, or re-setting the trip counter/elapsed time. Also, please note in the instructions that the “thin washers” for the front fork motor-drive are optional depending on the width of the fork. Thankfully customer support was able to help me in all of the above!

The Summit is performing just like I wanted. It really helps me get up some challenging hills and has greatly increased my biking enjoyment. The pedal assist works very well for my 20+ mile ride, which is all uphill for the first half. It took me awhile to figure out where to place the pedal assist sensor and I recommend more explicit instructions or a picture. My kit came with everything except the aluminum ring to hold the magnet wheel in place. Once I contacted them it was sent to me within a few weeks. They also informed me that backup batteries are not available for the summit. I would like to have one for when camping without electricity. Great product!

The installation process was tedious since the bike this was being installed in was custom. I had to build a bracket for the battery, but everything else was smooth sailing from there. The instructions provided could’ve been a bit more detailed, but otherwise made it the process slightly easier. First impression on the kit was delightful. I felt like a kid again. I couldn’t wipe the grin off my face. It is worth the buy. I can go much farther than before and not ever worry about hills anymore. I’m overall happy with this purchase.

I would highly recommend the Summit Electric Bike Kit. The kit was complete with everything needed to install it. The instructions were clear making it easy to install on my bike. Works great. Before installing the kit I didn’t think I wanted the throttle, but it really helps going up hills. I usually set the petal assist to one and cruise. It has gotten me back on my bike and pedaling to work.

I’ve only had the Hilltopper Summit for a few days now, but I am blown away by the power and control that it provides. With the 48v motor, I can ascend some hills with no pedaling, and very steep hills (40 degree incline or more) with some pedaling. I had a little bit of trouble with the installation, but it was absolutely worth it.

Awesome 👍 very fast, powerful, and fun!
