Award-winning gravel DNA, electrified.
Adventure Ready
700x58c (29x2.25") tire clearance and room for at least two bottles on every size.
Whisper-Quiet Power
The TQ HPR 60 drive unit adds a smooth, natural, lightweight assist for long, high-output days.
Modern Gravel
Suspension-ready, stable yet agile geometry, and an electric system that disappears into the ride.
Made For High-Output Days.
Everything you love about the Shafer, now with power for longer rides, bigger adventures, and more time with friends.
Performance, with a natural feel.
Shafer HP is a gravel bike first. It's stable and planted but still nimble, with engineered flex that smooths rough roads and the strength to take on singletrack. The assist is smooth and whisper quiet.
Go farther, go anywhere.
Gravel roads, asphalt, singletrack, commutes, or multi-day bikepacking trips. Shafer HP gives you the range and capability to chase the ride you're imagining.
Dust, determination, dirt-filled fun.
Power That Feels Like You
The TQ HPR 60 delivers 60 Nm of torque and 350 W of power in a drive unit that weighs just 1.9 kg (4.18 lbs). Choose Eco, Mid, or High to match the ride.
Range for Real Rides
A 360 Wh integrated battery gives you plenty of range for climbing on your favorite rides. 160 Wh range extender for even longer days in the saddle.
Proven Geometry, Evolved
Shafer HP is built upon Shafer's award-winning platform that keeps a stable, confident feel riders love.
Extended Rides
Add the optional 160 Wh range extender for bigger days. Plug it in and forget it. The bike switches power sources automatically, with no extra rigging and no manual swapping.
Wide Open
Clearance for 700x58c (29x2.25") tires with wide rims for added traction, comfort, and speed over rough terrain.
Frame & Features
Same geometry as the Shafer, built with Ari's CleanCast carbon layup and award-winning Monoform construction for a frame that's extra light and strong. It's backed by a Lifetime + Transferable Warranty.
Suspension Fork Ready
Compatible with suspension gravel forks and dropper posts, same as Shafer. It blurs the line between adventure and race.
Built for Every Kind of Ride
Commuting is covered with fender attachment points. Bikepacking and long days get extended range and gear mounts. Every size carries at least two bottles in the front triangle, and sizes M-XL carry three.

Common Questions*
Do you offer financing?
Yes, at checkout there are several options available for financing.
What is the warranty?
Each frame comes with a Lifetime Warranty. Ari branded frames come with a transferable warranty as well.
How does transferable warranty on Ari bikes work?
Ari branded frames come with a transferable frame warranty available to the second owner. The second owner can receive a one-year frame warranty from the date they purchase the bike from the original owner. Warranty only transfers once. All Ari bikes must have the transfer documented from the original owner to the new owner here in order to qualify for a transferable warranty.
Does a water bottle fit in the frame?
At least two full-size water bottles fit inside the front triangle on all sizes. There is space for water, tools, or bags, plus extra mounts on the fork legs so you can set your Shafer HP up for whatever ride suits you.
What kind of bike is this?
E-Gravel Bike. Where performance meets adventure. Complete bikes start at $4,199 for the Shafer HP Sport build.
How should I choose a size when buying online?
Use Ari Custom Setup and Ari will fit the bike from your body measurements. There is also a size guide in the bike builder, and the support team can help before you order. Details: Custom Fit.
Who is this bike for?
Shafer cyclists appreciate versatility in cycling, combining the love for both on-road efficiency and off-road adventure. This cyclist seeks the freedom to explore less-traveled paths, such as gravel roads, forest tracks, and light trails, without being limited by the capabilities of a traditional road bike.
How long will it take to arrive?
Estimated lead times are listed under each model's size in the bike builder. Times may vary a little based on current conditions, frame size, color, and availability.
What is the guarantee?
It comes with a 30 Day Love it or Return it Guarantee.
What is the assist speed limit?
Shafer HP is a Class 3 e-bike capable of assisting up to 28 mph.
Can I use a range extender?
Yes! A water bottle-sized 160Wh range extender can be added to keep your adventure going.
What does the starting price include?
Complete bikes start at $4,199 for the Shafer HP Sport build. The listed price is the complete bike at that build level; the bike builder shows the selected options, lead time, and any upgrades before checkout.
What about service?
You can work directly with us, one of our recommended shops, or work through your local shop.
What assembly is required when the bike arrives?
Bikes ship pre-tuned, test-ridden, and about 95% assembled. Basic at-home assembly remains, and technicians are available for help. See Support.
How will it arrive?
All Ari bikes go through our Custom Setup process, making sure the bike is fit and tuned specifically to you. They are test-ridden before delivery. If your bike is shipped to you, it’s still tuned and ready to ride and requires just a few minutes of assembly.
What do shipping, warranty, and returns actually involve?
Current terms live on the policy pages, not in this summary. Read Shipping, Warranty, Love it or Return it, and Return Policy before you buy. Outlet bikes follow different return rules.
What motor does the Shafer HP use?
Shafer HP uses the TQ HPR 60 drive unit to give you 60Nm and 350W of assist in a lightweight and quiet package.
Can the Shafer HP run a suspension fork?
Suspension gravel forks such as the RockShox Rudy XL, RockShox Rudy, 32AX, MRP Baxter, or Suntour GVX can be installed on the Shafer HP frame. You can add one during checkout on our website. If you choose to get one on your own later, we recommend running the longer fork offset option (as close to 50mm as possible). The stock fork axle-to-crown measurement is 440mm.
What are the dimensions of the rear hub and rear axle?
The rear hub is 142mm x 12mm. The axle dimensions are M12 x 167.5mm long x 15mm thread length x 1.0mm thread pitch.
Can the Shafer HP run an internal dropper post?
The Shafer HP can use an internal dropper post with a diameter of 27.2mm.
What size is the battery?
360Wh of gravel-grinding energy.
What tire sizes can I use on Shafer HP?
Clearance for days. Fits tires up to 700x58mm on a 30mm inner-width rim, or run up to 50c with fenders in commuter mode.
What are the headset dimensions?
The Standardized Headset Identification System (SHIS) is IS52 / 28.6 | IS52 / 40 (45°). This is used with the 1.5”/1.5” headtube. We have chosen to use the FSA SRS headsets for simple, clean cable management. FSA ACR is also compatible if the matching stem is used.
What are the dimensions of the front hub and fork axle?
The front hub is 100mm x 12mm. The axle dimensions are M12 x 118mm long x 14mm thread length x 1.50mm thread pitch.
