The eRoad Trinity of competitive sports, modern, and future.

It's a romantic race itself that countless humans have devoted themselves to, with strict training day after day, exploring scientific methods, equipment, and practices; finally facing the endless possibilities of the future and breaking all limitations.


Design Concept of R3 →

As much carbon fiber as possible

Frame, forks, handle bar, seatpost, and wheels, the Urace R3 uses high-modulus T800 carbon fiber as much as possible to reach the edge of lightweight, but high-strength and durability.

95% Integrated Cable Routing

Looking forward to the future bike trends, the R3 is designed to be internally routed to keep it simple but eye-catching. *The e-Derailleur and a part of the motor cable can't be hidden.

Patented cycling-power assist

Unlike regular e-bikes, which use a cadence sensor for commuting or a torque sensor for fun, the R3 focuses more on sports performance and improvement, like advanced riders always do.

Unique aero-optimized rims

Benefit from the wavy construction, the peaked sections provide a robust spoke connection for higher efficiency, while the troughs help reduce crosswind drag, slightly improving stability at high speeds.

Straight-pull spokes and hubs

Without the breakage point of J-bend spokes, R3's straight-pull spokes and hubs tend to last significantly longer in high-stress racing. And it slightly improves stiffness and responsiveness.

Front & rear 160mm disc brakes

Balancing the brake performance and gross weight, the R3's brake system uses custom mechanical hydraulic piston calipers with 160mm rotors, allowing a slight slowdown or rapid stop.

Responsive 11-S shifting system

R3 features the L-TWOO electric derailleur and SHIMANO RD7000 11-32T shifting system for smooth and responsive shifting. Then helps you make use of all skills and energy at any time.

Top tube integrated computer

Displays real-time riding data, keeps your handlebars and front vision concise. So it won't distract you from focused riding. *The calorie was estimated based on your pedaling power rate.

Removable lights & reflectors

To ensure you see and be seen, the R3 was designed with an auto-switch LED headlight, shark-gill side lights, and spoke reflectors. *The headlight can not turn off, but it can be removed.

R3 Sizing Chart

Your height and inseam are very important for a road bike fitting, so please measure carefully.
To measure correctly, you can stand straight up on your bare feet, with your back, heels, shoulders, and head all touching a wall.
Then measure the distance from the top of your head to the floor, and the inseam from the bottom of your crotch to the ankle bone.

Size Rider Height Inseam
XS 150 - 165 cm (59" - 65") 70 - 77 cm (27.5" - 30.3")

FAQs

Of course, there's no reason for a road biker not to cycle when it rains.
The R3 was IPX6 rated, and all cable/electronic connectors are waterproof. You don't need to worry about its function and performance in wet weather.

There are some tips for better riding in the rain. 1) Reduce the tire pressure to 65-70 psi; 2) Wear a cycling cap or goggles to keep rain out of your eyes; 3) Clean and dry the chain, freewheel, and chainring in time.

No, you shouldn't do that. The battery was made with LG21700 lithium-ion cells, which work somewhat like the battery of your cellphone.

Charging it after every ride (but no lower than 20%) to 90% of max capacity can be the best practice for both charging speed and battery lifespan.

Unlike other Eahora e-bikes. There's no throttle on the R3 e-Road, so riders can only ride it with pedal-assist mode. And the motor will stop assisting when the speed reaches 28mph (USA marketplace) or 25km/h (EU marketplace).

Sure, we have already completed the sample production and testing of the one-piece carbon drop handlebar. And now it's on the series of tests on the performance, compatibility, and durability. We will sell it (with the refit set) on our website after everything is ready.
