Colnago Y1Rs: Full Review, Price, Geometry, and Where to Rent It

The Colnago Y1Rs is Colnago’s commitment to high-end electric road bikes. In a market where e-road bikes have gone from being a curiosity to a serious category, Colnago has applied all its philosophy of performance and Italian design to create an electric bike that doesn’t compromise on anything: neither weight, nor aesthetics, nor the joy of pedaling. In this review, we tell you everything about the Y1Rs — and how you can test ride and rent it in the best cycling destinations in the Mediterranean.

What is the Colnago Y1Rs?

The Colnago Y1Rs is Colnago’s first electric road bike, developed in collaboration with Mahle, a German manufacturer specialized in ultra-light electric assistance systems. The result is an e-road bike that, unlike conventional electric bikes, maintains an aesthetic and behavior very close to that of a traditional road bike.

The Y in the name refers to Colnago's electric generation, while the suffix Rs (Racing Supremacy) connects it directly to the philosophy of the V5Rs. It is not a bike for riders who don’t want to pedal — it’s a bike for riders who want to pedal more, farther, and with more people.

Motor and battery: Mahle ebikemotion technology

The heart of the Colnago Y1Rs is the Mahle ebikemotion X35+ system, one of the lightest and most discreet electric assistance systems on the market:

Motor: Mahle ebikemotion X35+, integrated in the rear hub
Maximum power: 250W (European legal limit)
Maximum torque: 40 Nm
Battery: integrated in the down tube, 250Wh
Range: up to 100 km in eco mode (variable depending on terrain and assistance level)
Charging time: approximately 3-4 hours for a full charge
System weight: approximately 3.5 kg (motor + battery)

The great advantage of the Mahle system is its total integration: the motor in the rear hub is practically invisible, the battery is hidden inside the frame, and control is done via a mobile app or a discreet button on the handlebar. The result is a bike that visually hardly differs from a conventional road bike.

Geometry of the Colnago Y1Rs

The geometry of the Colnago Y1Rs is directly based on that of the V5Rs, with slight adaptations to accommodate the electric system:

Top tube: slightly sloped, aerodynamic design
Down tube: oversized to integrate the 250Wh battery
Rear stay: adapted for the motor in the rear hub
Available sizes: XS, S, M, L, XL
Compatibility: hydraulic disc brake with 12mm thru-axle

The riding position is similar to the V5Rs: aggressive and aerodynamic, designed for cyclists seeking performance and not just comfort.

Frame: Italian high modulus carbon

Material: high modulus carbon, monocoque construction
Frame weight: approximately 1,100-1,200g (including integrated battery)
Total bike weight: from 10-11 kg depending on build
Finish: premium paint with Colnago customization options

Price of the Colnago Y1Rs

The price of the Colnago Y1Rs reflects its positioning as an ultra high-end e-road bike:

With Shimano Ultegra Di2: from €8,000-9,500
With Shimano Dura-Ace Di2: from €11,000-13,000
With SRAM Red AXS: from €11,500-14,000
Top versions with carbon wheels: up to €15,000-17,000

Given the price, renting a Colnago Y1Rs is a smart option to find out if an e-road bike of this category fits your riding style, or simply to enjoy it during a cycling trip without worrying about logistics.

What type of cyclist is the Colnago Y1Rs for?

The Y1Rs is not a bike for cyclists who don’t want to make an effort — it’s for cyclists who want to go further:

Cyclists with different levels in the group: assistance allows leveling the pace and enjoying together
Cyclists recovering from injuries: pedaling with assistance without losing the road bike feel
Traveling cyclists: perfect for long routes in destinations with elevation like Girona or the French Riviera
Cyclists over 50 years old: maintaining pace and distance without the physical wear of before
Enthusiasts who want to explore more: reaching climbs and destinations that were previously out of reach

Colnago Y1Rs vs Colnago V5Rs: which to choose?

Colnago V5Rs: traditional road bike, maximum lightness and pure performance, for cyclists who see effort as part of the experience
Colnago Y1Rs: e-road bike with discreet electric assistance, for cyclists who want to go further, longer, and with more people

Both share the same Italian design philosophy and the same build quality. The choice depends on your goal: pure performance or freedom to explore.
