    Discover Assembly Manual

     

  • Simply said, a gravel bike is a combination of a road bike (happy on smooth pavement) and a mountain bike (happy playing rough and tumble in the mud). Mellow single tracks, farm roads, gravel, crushed cobblestones, rough city streets, tarmac — whatever. A gravel bike is a machine that's capable of performing on various surfaces, while sustaining comfort.

    Gavel bikes like the Discover have 650b wheels with wider tires that run at a lower pressure, a slightly more upright posture, and thicker forks that can handle rougher roads. These small changes give a road bike like performance with more comfortable riding on un-paved roads. Gravel bikes like the Discover also have braze-ons (holes for screws) for connecting front and rear racks, and are a popular choice for road cyclist on long rides, bike messengers, urban commuting with bags or kids, bike camping, and long distance touring.

    It is important to note that a gravel bike is NOT a mountain bike and does not have shocks and cannot take jumps, or big drops. It is still a road bike and intended for on-road use. The definition of what it means to be "on-road" is just much broader then your typical road bike, giving you the freedom to explore some wild and beautiful places.

  • 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 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 Horizon HillTopper electric bike conversion kit is another step up from our Sprinter kits. This kit offers higher power and more 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 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. 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.)
    7. Use one of the thin cable with yellow plugs to connect the battery to the throttle.
    8. 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.
    9. 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!

    5. Connect it all with the two plugs on your Cable Set.

    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!

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.

     

  • 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.

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.

Replacement Parts

  • Missing hardware or any other small/miscellaneous parts? Please contact our Customer Service team at support@hilltopperbikes.com to see what we can do to get you fixed up and ready to ride.

  • Whether you charger wandered off, or you notice that you throttle or cables are damaged there is nothing to worry about. All of these parts are easily replaceable by ordering online, or by contacting support@hilltopperbikes.com

  • If your battery is wearing out, replacement is easy. A replacement can be ordered online, or by emailing sales@hilltopperbikes.com

  • Is your wheel bent? That's a bummer, but not to worry most any bike shop can fix you up!

    If the wheel just has a little wobble to it, take it to your local bike shop and ask the to "true" it. Most bike shops can take care of this pretty quick with a reasonable service fee.

    If you think the wheel is really bent, truing it may not help, but still worth getting an expert opinion at your local bike shop. If it turns out it can not be trued, then a rim replacement is likely needed. You can either purchase one of your choosing from your bike shop, you can email support@hilltopperbikes.com to purchase an identical one. Once you have a new rim on hand, you bike shop can easily lace it up to your existing hub/motor.

Will It Fit My Bike?

  • 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.

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

  • 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", 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.

  • For our conversion kits, and on some of our bikes, we offer two methods for controlling the motor manually, the GripSwitch, or an Adjustable Speed Throttle. Both serve the same purpose, but go about it differently and offer different installation options.

    Adjustable Speed Throttle:

    • Controlling the motor work just like a gas pedal in a car. Push it all the way for max speed, push it just a little for lower speeds. This means that just like in a car, you are in total control of your speed, but also means the more aggressive you "drive" the less "gas" mileage you may get on a full charge.
    • Installing the throttle is a little harder than the GripSwitch, but still pretty simple. It does require that you remove your handle bar grip first.
    • When considering the Throttle option, keep in mind that it has a maximum clamp diameter of 22.2 mm. This means there can be complications installing it on drop bars for handle bars with a larger diameter.
    • Not compatible with our older 24V conversion kits or electric bikes.
    • If you are interested in upgrading your old 24V kit to use this type of throttle, please see our new Universal Replacement Battery pack. Update to a 36V battery to use this throttle.

    The GripSwitch:

    • Only available on our 24V electric conversion kits and bikes from 2019 and earlier.
    • Easiest possible installation ever conceived. Just strap the Velcro where ever you like on your handle bars. This means it can go on the right-hand or left, top or bottom, middle or end. Many people place it to be pushed by thumb, others like to set it as a trigger under their index finger. The possibilities are nearly endless and the choice is yours.
    • Compatible with absolutely any handlebars.
    • Controlling the motor is equally simple. Since it is a button, it's just on or off. Just hold the button when you want a boost, release when you don't. We have fine tuned the motor controller to conserve energy, minimizing wasted power to keeps you rolling longer.
  • The 36 V HillTopper electric bike conversion kit is a step up from our original systems both in tech and performance. The bigger motor offers more power while the Horizon battery give you more miles on the road and 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. Unlock and remove the battery from the mount(Horizon and Sprinter Bottle Only).
    4. Affix the battery mount to your bike's water bottle mount or a rear carrier, then reattach the battery.
    5. Remove your your handle bar grip. (You can choose right-hand or left, it's totally up to you.)
    6. 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.)
    7. Connect it all with the two plugs at the ends of your Cable Set.
