Discover New Possibilities

Discover the Road Less Traveled

An Electric Gravel Bike Built for Adventure

Whatever riding you like to do, be it city streets, or gravel farm roads, the Discover will get you there and back in comfort and style. We designed the Discover to be lightweight and maintenance friendly. The drivetrain is a 1 x 9 system that eliminates the front derailleur while giving you a wide range of gears in back for tackling the hills. And our 36V 350W rear hub motor will give you all the assist you need. We also made sure the Discover has all the attachment points you need to outfit your bike with fenders, lights, racks, bags, and water bottles of your choosing. We are even providing a front rack to get you started.

What is the Difference Between a Gravel Bike and a Road Bike?

The Discover rides the middle path between the mountains and the road

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, pot holed city streets, tarmac — whatever. The Discover is a machine that's capable of performing on various surfaces while sustaining comfort. For us here at Hilltopper we see the Discover as the perfect bike for those who love to ride and want one bike for all their adventures. To unite their passions, and discover new ones.

Cutting Edge Technology Meets Minimalist Design

Low-maintenance & High Performance Drivetrain

Integral to the performance of the bike, the Discover boasts a modern 1 x 9 drivetrain system. The Microshift Advent system has an advanced, smooth shifting rear derailleur with an innovative clutch design. The 9 speed cassette has a wide ratio, 11-42T, allowing you to find the right gear for the right terrain. The Advent shifter uses cartridge bearings in the lever mechanism for better feel and more precise shifts. The entire system is designed from the ground up by Microshift to be user friendly and maintenance light to keep you on the road and riding.

Powerful & Compact Electric Motor

Discover your hidden super powers, one pedal stroke at a time

At the center of things is the Hilltopper Discover 36V 350W rear hub electric motor. Small & compact with a high torque to size ratio, this motor provides a sustained 20 mph cruising speed and higher with pedaling. The torque is roughly equal to two soul cycle instructor's combined pedal power. The rear motor also has a built in speed sensor for a smooth transition of power. Hilltopper motors are legendary for their long lifespan and are maintenance free.

The power to go further, play harder, last longer

Battery range of 30 - 55 miles in a sleek, integrated design

Powering the motor is an advanced 11.4Ah lithium battery. The battery is integrated into the down tube for a sleek design and low weight distribution for better handling. It is easily removed for charging and the keyed lock keeps it safe and sound on your daily errands.

You're in control

We have you covered even if your legs get tired

Throttle or pedal assist? We designed the Discover to have both so you don't have to choose. The PAS (pedal assist system) gives you power with each pedal stroke. Choose 1 of 4 levels assist to get you where you need to go. And hey, if the legs can't make it up that hill or you need to quickly accelerate through the intersection, the throttle is there to give you a hand. How fast are you going? What is your battery life? The small sleek LCD screen gives you all the information you need to explore that next bend with peace of mind.

Choose Your Size

Designed for Comfort and Performance

We want to make sure everyone is able to ride that is why we built the Discover in two sizes. The small / medium frame comfortably fits men and women 5'0 to 5'8. The large frame comfortably fits men and women 5'8 - 6'5 and over. With an adjustable saddle, and seat post the Discover easily accommodates many body sizes and riding styles. At 44 lbs the Discover is also one of the lightest e-bikes on the market, making it easier for everyone to carry up stairs, load onto a bus or train, or lift onto a car rack.

Components

  • Microshift Advent 1 x 9 with 11-42 wide ratio cassette, clutch rear derailleur, and narrow wide chainring to prevent dropped chains.

  • Hilltopper 36 V 350 W brushless rear hub motor with built-in speed sensor.

  • Tektro mechanical disc brakes w/ electric cut off

  • Enjoy a boost every time you pedal. The pedal assist sensor gives you 4 levels of assist, and the twist throttle gives you the power when you need it. The 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. Elegant handlebar layout and minimalist components give the Discover a clean, sleek cockpit for touring and long rides while having plenty of power at your finger tips.

E-Bikes

  • 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 (Ranger & 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.

    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).

But its a lot of fun and gives you the peace of mind that you can accelerate out of any sticky situation.

    • Aluminium frame to save weight, with a steel fork for strength and durability.
  • 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.
    • For all returns or warranty claims contact support@hilltopperbikes.com
    • 30-day money back guarantee. Returns of undamaged conversion kits may be issued full refunds less a $50.00 restocking fee. Returns of undamaged complete bikes may be issued full refunds less a $125.00 restocking fee.
