" I think FLX has nailed a very desirable pricepoint with its bikes. There's a big hole that they are filling with a beautiful and quality product. "
Paul D.


" Did a father son dirt track ride today on my Trail. The FLX is great on the road but it’s a real BEAST on the trails. I was blasting uphill on segments where my legs would normally be burning with lactic acid. I can now keep up with my son’s energy level :)! "
Hammed M.


" Wife absolutely loves her FLX! We can now ride together. Until the hills then she takes off. Amazing experience! Worth every bit of the wait and $$$. Just gotta get my own one now. Thanks FLX Crew. "
Caleb R.


" Awesome time today in Santa Cruz on our FLX Trails! 25 miles and still had half battery!!! Most fun we’ve had all summer! Thanks guys! Best bike ever! "

Front Suspension
FLUX so hard the ground will shake under your feet. If you live on a fault line though, that might be serious. Seek shelter. Own the downhill, tear up the park and get ready to smash some records with the SR Suntour XCR Suspension.

Story

Hi, we’re Pete Leaviss and Rob Rast, founders of FLX.
We’re on a mission: To get people out of cars and back onto bikes.

eBikes are revolutionizing the way people commute and enjoy longer rides. Key factors in getting more people on bikes.

We are so insanely committed to building the best eBike on the planet, we moved into the factory for several months to oversee quality control and personally inspect every single bike that comes off the line.

Attention to detail, awesome community, and quality components make FLX the best eBike on the planet.

But don’t take our wordread the reviews.

Testimonials

Hammed Malik

Did a father son dirt track ride today on my Trail. The FLX is great on the road but it’s a real BEAST on the trails. I was blasting uphill on segments where my legs would normally be burning with lactic acid. I can now keep up with my son’s energy level 🙂

Todd Pollock

The great thing about this bike… and something I didn’t expect is that I am getting more workout than I have in a long time… just because I’m now willing to go out with my (15 yr old) boy. He used to burn me out and it wasn’t fun for either of us… but now I can use whatever assist I need at the moment … but am sweating and getting a workout while smiling! Thanks FLX!

Caleb R.

Wife absolutely loves her FLX! We can now ride together. Until the hills then she takes off. Amazing experience! Worth every bit of the wait and $$$. Just gotta get my own one now. Thanks FLX Crew.

Ed Garces

I finally got the time to take the Attack to a real Mountain Bike Trail at Makawao Forest Reserve in Maui. The trail was quite narrow and twisty going downhill. Going up was fun as I passed a few bikers who were struggling to pedal up very slowly. They probably thought I was Lance Armstrong as I whisked by at a good clip before they could even say hi. My FLX Attack felt solid at all times and yes I got a few thumbs up at the parking lot too.

“I have been researching for nearly 5 years, but never spent the money until the FLX Bike came along. And, now I’m sold! We have 2 bikes on the way now!”- Nathan Long (happy customer x2)

What makes FLX a superior eBike?

High Capacity Lithium Batteries

FLX is powered by the same battery cells as the Tesla Model S.

*Our lawyers said we had to note it’s technically not “Tesla” brand batteries… Because that’s not a thing.

MId motor

Many eBikes use a hub motor in the wheel because it’s cheaper. It’s also far less efficient.

Well screw that. FLX uses a “mid-motor” mounted between the pedals. This allows the motor to take mechanical advantage of the 9 speed Shimano gears.

Ultimately, giving you a smoother, more powerful ride.

hydraulic disc brakes

eBikes are much more powerful than normal bikes. For safety as well as performance, every FLX bike includes hydraulic disc brakes.

Passionate Community

 

What really made FLX a huge success? The fans!

Many people called the FLX crowdfunding campaign the most fun they’ve ever had backing a project.

PRAISE FROM THE PRESS

It might just be the best electric bike option out there.
– The Upscout

 

We’ve seen our fair share of ugly bikes whose batteries looked like they’ve been designed as ugly as possible on purpose, but with FLX, this has completely changed.
– Autoevolution

 

 

A wonderful team… Creating affordable, yet functional E-Bikes!
– MtnBikeGeek

 

The central motor has advantages over hub motors, because of the more even weight distribution and the ability to utilise the bike’s own gears to optimize torque in any speed.
– Spycycle

FAQ

I'm short or tall, will FLX fit me?

Almost always, yes. We’ve had riders as short as 5’2″ and as tall as 6’5″ test ride, love it, and buy a FLX. The secret is in our frame design with a dropped top tube and angled seat post. As you raise the seat, it pulls back farther from the handlebars.

What if something breaks?

We use high quality components that can be ordered online or picked up at any local bike shop. For electronics, we will ship you replacement parts that you can take in to your local bike repair person. We will pay for any repair costs under warranty.

Does the bike come with a warranty?

Absolutely. We’re extremely confident in the bikes’ build quality and sourced components. All bikes come with a 1 year warranty.

Can the bike get wet?

Yes! We take our bikes through mountain streams and rain almost everyday. The motor and electronic components are sealed and built to take a beating.

What is the range of the battery?

With the 17Ah battery, you can ride for 46 miles on full power (pedal assist level 5) based on actual 3rd party tests vs made up manufacturer claims. Many customers are reporting 85-100 miles when they ride in pedal assist level 2 or 3. No other eBike in this category can beat the actual range of FLX.

What is the power output of the motor?

All FLX bikes now have a massive peak power output of 650W.
