The motor is able to read the rider’s input power, and it can be sent to your computer and produce a power metric. And when I say that, I’m not exaggerating! On day one we rode so hard on the climbs and even the flats that day two started out super mellow since everyone’s legs were still tired. Both rides would be challenging on any bike, and the one thing that stood out most to us on the rides was that we didn’t go any easier we just went faster. We had two days’ worth of rides planned in Santa Cruz-the first was a 50-mile road loop that had over 6000 feet of climbing, while the second was a 45-mile mixed-surface and gravel ride with about the same 6000 feet of climbing. While we’ve had a lot of e-bikes come through the well-lit penthouse offices of Hi-Torque, thanks to Electric Bike Action, few are up to the task of matching real-world ride expectations and weight targets like the Creo SL. Overall the system is a balance between power, efficiency and weight. The new SL1.1 motor weighs (a claimed) 4.3 pounds, owing to its magnesium casing and refined design. For comparison, the competition has a peak efficiency of only 60 percent, and that is in a very narrow and low cadence that doesn’t translate to traditional riding. ![]() The optimal and most efficient power range is between 80–90 rpm at 84-percent efficiency, and the most total power output is at 100 rpm. The motor has been tuned for riding cadences between 60 and 110 rpm, and maintaining over 80-percent power efficiency throughout the whole range. The big news here, and the reason the Creo SL is able to get so much range out of such a small package, is its unparalleled efficiency. Both S-Works models will come with the bottle cage battery, as well as the internal battery, while the rest are only available with the internal battery. Using the Specialized Mission Control app allows each of these modes to be customized. There are four assist settings-off, Eco, Sport and Turbo-that are controlled with a top-tube-mounted control unit. The internal battery can be removed for airline travel or to lower the bike’s overall weight. There is a 320-Wh internal battery that puts the range at 80 miles, with an optional 160-Wh external bottle-cage-mounted battery that can add another 40 miles of range (again, depending on conditions like rider weight, wind and topography). The new motor, while much less powerful than the other motors at 240 watts and 35 N/m, is extremely efficient. It is worth noting, however, that unlike the Specialized, you can swap out the rear wheel of a bike with a rear-hub motor (e.g., Bianchi Aria E-Road, Pinarello Dyodo, Orbea Gain, among others) and automatically lose a majority of the added weight and be left with a close-to-traditional pedal bike.Īfter relying on a partnership with Swiss motor maker Brose for their previous efforts, Specialized told us they felt restricted by the design constraints of their partners on their previous Turbo bikes, so this is an all-new motor platform (with a new partner) that they have been working on for a while now. We’ve ridden a few e-road bikes with rear-hub motors that are about the same weight, but none offer the promise of 80 miles of range on a single charge (depending on conditions) as the Creo SL does. One of the most impressive numbers mentioned was the bike’s weight, hitting the scales at just under 27 pounds for the 54cm complete build. The 1x-specific drivetrain uses a Praxis crank, and all the current builds use Shimano shifters, brakes and gearing. This means finding wheels other than those Specialized offers is currently nearly impossible. New to Specialized is the use of what they call “boost road hub spacing” with a 110x12mm front and 148x12mm rear thru-axle. ![]() The other three models will be road-oriented, but since they all share the same frameset, you could modify the setup to your liking if you have any cash left, which will be a challenge for most of us.Īll the bikes use the front Future Shock 2.0 fork (with 20mm of travel) that was recently launched on the new Roubaix. The Creo SL is available in four models, one of which is gravel-ready with a dropper post and 38mm tires. The overall geometry is very similar to the Diverge with a low bottom bracket and room to fit up to a 42mm tire. The new Fact 11r carbon Creo SL frame combines much of the knowledge that Specialized acquired from their non-assist road and gravel bikes when it comes to construction and geometry. The Turbo Creo SL EVO is built for gravel and multi-surface riding with 38mm tires stock and a dropper seatpost.
