  • 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.

    Gravel 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.

  • When you buy a bicycle from Hilltopper we donate a bike in your name to a child in need here in Seattle. Your gift of a bicycle helps young people develop self-reliance, leadership, and life skills at BikeWorks.org, a community driven non-profit here in Seattle. Low-income children at Bike Works receive their donated kids bike at a family bike swap. Teens receive their donated bike as part of the Earn-a-bike program, where they learn how to build and repair bicycles, put their new skills to good use by volunteering to help others fix their bike, and earn a new bike at the end.

    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.

Kali Bike Helmets - UNAVAILABLE

SOLD OUT - THIS PRODUCT IS DISCONTINUED The Saha is designed for commuters first and foremost with a durable, long lasting design and clean, minimalist look. It complies with safety standards to keep you protected as you navigate crowded bike lanes and fast-moving traffic and comfort features including venting along the top of the helmet, a dial system for customized fit, and washable padding for a dose of plushness. Though it boasts an ecologically-responsible construction, the Saha's main goal is still protecting your head. Kali makes sure it's more than adequately equipped to do this by heat-molding a corn-based polymer known as Polyactide into a hard outer shell, then complementing it with 100% recycled Polystyrene inner foam to mimic the effective construction of more conventional helmets, which usually feature a hard plastic shell backed by EPS foam. It keeps you safe, while also reducing the amount of plastic waste and impact on our planet. S/M fits heads 21" - 23" inches in diameter and L/XL fits 23" - 24.5 inches.
