Specialized Turbo Levo FSR 6Fattie/29 Comp
Priced right at $4,500, the Specialized Turbo Levo FSR 6Fattie/29 Comp may be a mouth full but more importantly it promises to deliver a quality trail riding experience you would expect from its non-motorized counterpart.
First let’s break down its fantastic name:
- Specialized bikes as we all know has been making ‘Epic’ mountain bikes since 1974 and was founded by Mike Sinyard who remains as its CEO today.
- The Turbo series is Specialized’s electric-assist bike line.
- The Levo is Specialized’s off-road line in their Turbo series.
- The Turbo Levo series features three assisted settings: Turbo, Trail, & Eco mode.
- FSR refers to Specialized’s full suspension technology but it’s important to note that all current FSR models feature 150mm front travel and 135mm rear wheel travel, their M5 alloy frame and the same motor unit (although the S-Works version has an upgrade battery).
- 6Fattie is Specialized’s three-inch wide tires mounted on 27.5-inch wheels. The fatter tires mean the wheels measure to about the same as a 29er, but they allow for lower tire pressures and the resulting traction benefits.
- 6Fattie/29 is actually a pretty cool feature that decreases deflection and dramatically increases traction and it allows you to swap between 29-inch wheels and 6Fattie wheels. This feature makes this bike more configurable for different riding styles and/or conditions which ultimately is a big plus in the fun zone.
- Comp refers to the component build of this model which is built around a SRAM GX 1×11 component group.
Phew, with that covered we will now affectionately refer to this bike as the STLFSR6F29C
The STLFSR6F29C makes it easy to switch between assist modes by using the buttons on the left side of the battery unit. As with most electric mountain bikes this one is a pedal assist which means there is no throttle and it increasingly matches your effort. So as you pedal harder, the system throttles up, and if you coast – the system turns off. Specialized system targets both speed and torque which is measure (respectively) with a magnet in the brake rotor and a built in power meter.

Taking technology to the next step STLFSR6F29C features Bluetooth connectivity that allows the rider to adjust the level of assist in each mode, tune how quickly the assist is delivered, change modes, run diagnostics on the battery & motor, and even connect to Strava to automatically upload rides with the option to tag them as e-bike rides all via an app. The app also has a setting call Smart Control which allows the rider to enter specific parameters that can do things like extending battery life by decreasing the pedal assist for longer rides. Battery run times will depend on the modes used, rider weight and terrain, but typically 5,000 feet of elevation gain per charge is possible.
The STLFSR6F29C handling is great. This bike falls right inline with the latest FSR 6Fattie feel and features a high bb with short cranks to allow you to keep your cadence up which keeps the pedal assist in full effect. The setting allow the rider to custom tune how much help you receive so you can have full control over how hard your workout becomes.
The pedal assist part makes going anywhere fast and incredibly fun.
Uphill: This one is a no brainer, I pedal and the STLFSR6F29C begins to feel more like a lightweight motorcycle allowing me to spin right up steep rock faces that would have normally pushed me to my limits. The pedal assist part makes going anywhere fast and incredibly fun. Trails with agonizing long climbs no longer seem so impossible and those epic long rides actually become realistic to start planning for. Although the STLFSR6F29C taps out at 20mph, you will never find yourself feeling like a climb is moving at the dangerously slow crawl speed.
Downhill: Now not so revolutionary as going up since now the fun factor is noticeably vacant. Although this bike is still a blast to descend, and handles exceptionally well, I am moving a bit slower than normal. The extra heft become a burden in fast turns and the pedal assist is only ‘assisting’ when I’m pedalling, makes sense right? So now this bike feels reminiscent of the heavy DH bikes from the early 90’s but at least I have the hill climb to look forward to.
All around the STLFSR6F29C is a great bike and where it really shines is the fun up and down rolling trail systems that offer a lot of pedalling opportunities. Keeping the flow is the high point of the STLFSR6F29C, oh and climbing really steep stuff.
Brand Key Features
- The frame was constructed from our M5 Premium Aluminum, which is equal parts, strong, lightweight, and incredibly responsive. The design of the frame itself revolves around our Trail 6Fattie Geometry that includes all of our trail hallmarks, like a low-slung bottom bracket, roomy top tube, and ultra-short chainstays. Cable routing is all internal, including that of the Command Post IR, while the battery is fully integrated in the down tube and the motor is secured by a forged brace mount.
- The custom Specialized 1.3 Rx Trail-tuned motor is built for the Levo and features a 15% power increase and a significant efficiency increase compared to the Specialized 1.2 motor. This successfully places it at the top of e-bike motor technology. It has many other features that no other e-bike can touch, like instant engagement, fantastic heat management, a double freewheel design that disengages the gear box when you hit top speed, and silent, smooth, and consistent output—even at max power.
- The Specialized M1-460 battery features an integrated Trail Display, ANT+/Bluetooth® module, and Mission Control App connectivity. It also houses 460Wh of trail-taming juice, and it’s neatly integrated into the down tube.
Although the added weight can be felt whilst measuring against the STLFSR6F29C's technical handling characteristics, within a few pedals the assit kicks in and any sign of the extra mass quickly fades away with the dust left behind as you rocket down the trail.
