Turbo Vado SL 4.0


Turbo Vado SL 4.0

Meet the Vado SL. This super-light e-bike was designed to take on anything from daily commutes through urban landscapes to clocking even faster workouts. Need to carry your bike? No sweat. Weighing 40% less than the full-power Vado, there’s no other electric bike out there with ride quality, range, and power like this. All you need to do is get on and go.

The Vado SL comes equipped with everything you need to start riding right away. First, the extra-bright, built-in lights give you higher visibility in low-light areas. Next, the MasterMind Turbo Control Unit (TCU) makes it easy to view ride info on the go. The Pathfinder tires roll fast on or off the pavement with plenty of grip, and the Vado SL's featherweight status also makes it perfect for city commuting and offers far more than ride quality — it means you can hang it on a wall or car rack. And it makes public transportation a breeze.

So whether you're going fast or far or both, the Vado SL provides the confidence to do it all at a fraction of the weight.

LIGHT WEIGHT: You’ll be blown away by how easy it is to lift your bike on to a rack, carry it up stairs, or ride nimbly around town, thanks to the category-leading light-weight of the Turbo SL technology, optimised frame materials, design, and specification.

COMFORTABLE AND CONFIDENT: Body position and handling are optimized to deliver unsurpassed riding comfort, confidence, and control. Powerful hydraulic disc brakes reign in your speed, while larger tires provide maximum traction for turning and stopping.

TURBO SL: The heart of the Vado is its Turbo SL technology, the advanced and integrated electric bike system that delivers an unequaled combination of light-weight, natural feel, anti-theft functions, training tips, a full-function bike computer, ride anywhere range, and more.

The speed limit at which the motor will stop supporting may vary significantly by region and is based on local requirements. It may also affect range: a higher speed limit may result in less range.

A little help when you need it.

I'm 76 and have not used my road bike since I got the Vado SL. I enjoy the freedom of not having to clip in and the comfort of a more upright position. I have over a thousand miles over mostly flat terrain. I enjoy that I can ride even if its windy. I try to stay in Eco mode because I do want some kind of a workout when I ride. However, the most fun I've had is riding to the top of Vail Pass in Colorado. The ride up is about 10 miles (used Turbo a couple of times). The ride down is fantastic, of course. I only used about 50% of the battery. The bike is so light that I get away with a trunk mount carrier.

Hi purchased this bike in Dec 2022 in order to ensure I had a bike for the 2023 summer. It has been in repair since June.. and still waiting on a new motor that they say won't arrive until October, and possibly later. I am very disappointed with this purchase. The bike is now on sale... and so paying full price for a bike that does not work is extremely frustrating.



Don't think you'll go the distance? Turbo Vado SL 4.0

You're correct. Just bought this bike for my wife. On our first ride (today), she rode 32 miles... and then the battery died. So, add the price of the extra battery if you want to consider this bike. Weak sauce considering it was the "up to 80 miles on a single charge" that convinced me to purchase the bike. Seems they rate downhill with a tailwind.

Vado SL 4.0

I have never enjoyed riding quite so much! I took advantage of the sale price and purchased a Vado SL 4.0. I utilize the bike for (in my opinion) its intended use as a 'fitness bicycle'. While Class 3 this bicycle has a relatively low(er) powered motor it is quite capable of 'assisting' a fitness minded rider. This model is FIRST an analog bicycle and secondarily an 'ebike'. Most of my rides are completed 50+% with assist completely off. Unless you are QUITE fit and capable of heavy exertion you should not plan on motoring around your city at 25+mph. At 33lbs...a capable and wonderful ebike for fitness minded cyclists.



Wonderful bike

I've rode a couple hundred miles and absolutely love the vado SL 4.0. It goes fast. It helps when you need it. I set the power controls to 100-40, 100-70, and 100-100 and this suits me well. Sometimes I turn assist off. Great bike. Wife loves her step through too.

Riding for 8,000+ miles so far..

Initially, I found the ride to be harsh and jolting riding over anything but smooth asphalt. If I had a time machine I would spring for the 5.0 for the future shock stem feature. In order to smooth out the teeth rattling jolts over bumps & pot holes, the seatpost was replaced with a redshift shockstop suspension seatpost. Cons: not easy to make even minor changes to the initial setup. Examples: to change the saddle the wiring to the rear light has to be disabled which is connected to the main battery. This bike has no seat collar clamp, which gives an elegant look, but is impractical. The seatpost is tightened from the top tube. When removing or changing the seatpost, the screw assembly falls into the seat tube 99% of the time. Then it has to be fished out (magnets sometimes work, but not always). Overall quality is excellent. After 2 1/2 years & 8,000+ miles the battery has 100% health and has had no mechanical issues. Bottom line: Fun, fun, fun to ride!

Perfect amount of assist

I've had this now for 1000 miles. I use it primarily for commuting. So far I've deleted the front headlamp. Didn't like that it's always on. Also threw on some continental terra speed 40mm's. Tubeless. Rides like a dream now. This bike allows me to put in the same effort, but now I get home in 1 hour vs 1.5 hours from work.

Great Bike But …

Great lightweight ebike however disappointing and surprised that a Specialized rear rack is not even available for the VADO 4.0 SL … I put a planet bike eco rack on my bike … In addition had to purchase a kickstand as well …

Missing that little kick ?

I'm 64. This bike makes me feel 34. It's does what is needed: Support on hills and against the wind. I have been using it on 35 support / 100 power only on the app, and that gives about 40 miles range. Everything is good on stock bike ( Vado SL 4.0 ). Only added pedals and bottle cage. I have a fancy ass gravel bike with bowed seat stays, and this bike rides almost as good. Think I'll sell the gravel bike.

Feels like a regular bike

With 500 miles since last June, this ebike is a dream to ride. Smooth, just the right power, and haven’t used more than 75% battery on rails to trails rides up to 65 miles, with 20lb of panniers - and that’s without the range extender battery! Never thought I’d want or need an ebike and others we looked at were like tanks. Best part, it weighs the same as my 34lb Trex 8.4 DS, which I’ve been riding for many years. So even if the battery did run out, I wouldn’t know the difference and wouldn’t be pedaling a 60lb bike back to the car.
