This post discusses the fastest electric bikes in the world. However, most e-bikes are NOT allowed on public roads or land as they are not fitted with a speed limiter, as required in most countries. In the UK, Europe, and Australia, this limit is 15.5mph. In the USA, it is 20mph. Learn more about e-bike laws here. The electric bikes discussed in this post can only be used on private land.

If you’re looking for the fastest electric mountain bikes in the world, then you’ve come to the right place. We’ve scoured the globe’s ever-changing mix of fast eMTBs to give you 7 of the fastest models available.

As we’ve already included in our disclaimer above, it should be noted these electric bikes should only be used on private land. Street-legal electric bikes are speed-limited.

What to Consider When Buying a Fast Mountain Electric Bike?

Electric MTB Power & Speed

Although it’s perhaps an oversimplification of things, ultimately the more powerful the motor fitted to an e-bike, the faster it will go. This is why the fastest MTB ebikes have extremely powerful motors.

Charging an Electric Mountain Bike

Like other fast electric bikes, and all electric bikes for that matter, charging a fast electric mountain bike is a simple process. Most e-MTBs can be charged by connecting a cord to the bike directly, or removing the battery and taking it to the plug socket. Be aware charge times can vary dramatically between different models.

Fast e-bike Mountain Range

Unfortunately, the fastest mountain electric bikes, aren’t going to have the greatest range, nor are they going to be cheap to run per mile. Like fast folding electric bikes fast e-bikes are focused on doing just that, going fast.

Are Electric Bikes Good For Mountain Biking?

Arguably electric bikes first caught on in the arena of mountain biking. They enabled riders to spend less time on the uphills and more time enjoying the thrills and spills of downhill riding, or flowing singletrack.

These days, the best electric mountain bikes are hyper-specialized, whether that’s ultra-lightweight machines for long-distance cross-country riding, or uber-powerful beasts for summiting the toughest of gradients.

  • Max Speed: 65mph
  • Weight: Not stated
  • Range: 100 mile
  • Gears: 20-speed

No skimping on components

9000W motor

‘Mullet’ wheel setup

After producing a very limited run of the Revolution XX, a bike which was capable of reaching speeds over 70mph, HPC decided to release another high-speed bike, the Revolution X9 Special Edition.

In our opinion this bike isn’t just about pure power either – yes its has 9000W motor – but it has other interesting component features that have clearly been chosen to help the bike perform when ridden at speed.


  • 20 speed gearing
  • 100 mile range
  • 4000W headlight


  • Rear hub motor doesn’t deliver the best ride feel
  • Bronze colour is standard though it can be customised

2. Hallomotor FC-1

  • EU Flag €5,600

Prices are approximate

  • Max Speed: 65mph
  • Weight: Not stated
  • Range: 65-75km
  • Gears: 1-speed

High top speed for price

Full suspension design

Different builds available

Coming in at number two on our list of the fastest electric mountain bikes is the Hallomotor FC1. Like all bikes on our list, with eye-watering top speeds, caution should be exercised at all times when riding them.

The FC-1’s top speed is thanks to a massive 5000W motor which is housed in the rear wheel of the bike.

Like most high speed electric bikes, the FC-1 has mountain bike cues in its design with suspension at both the front and rear. Large disc brakes ensure the bike can be brought to a stop from the very high speeds it can manage.


  • High speed e-MTB for the price


  • Specification not clear
  • Single-speed gearing renders the bike almost unusable without power

3. HPC Revolution X

  • Weight: 35.8kg
  • Range: 50 miles
  • Gears: 10-speed

Up to 65mph top speed

Upgraded motor

Sold US Class 2 compliant

Another HPC or Hi Power Cycles e-MTB is on our list. The Revolution X is HPC’s bread-and-butter full-suss model that can be brought in various motor powers. The standard 6000W version can hit speeds of 55mph, with the 7000W and 8000W motor versions delivering much faster speeds, albeit at a higher price point.

It’s nice to see that HPC allow you to customise the look of the Revolution X. Indeed, the frame is available four standard frame colours at no extra cost. Custom colours and matched wheel rims can be added for a further cost.


  • US Class 2 compliant
  • 60mph top speed is FAST


  • Pricey before you get to the optional upgrades

4. Stealth B-52

  • Weight: 64kg
  • Range: 60 miles
  • Gears: 9 speed

2500W motor

Decent range

Motorbike grade braking

Somewhat cheaper than other bikes on our list and arguably also the best looking, the Stealth B-52 is the fourth bike on our list.

Running a rear hub motor the bike is capable of speeds up to 50mph when using its electrical assistance.

As with all of these fast electric mountain bikes, they require huge onboard battery power to deliver rapid forward momentum. As such, the bike weighs a staggering 64kg.

The B52 is available in two frame colours, pitch black of pitch black fluo.


  • Strong looks
  • Acceptable range
  • Priced around the 5-figure mark


  • Hub motor is basic

5. HPC Scout Pro

Mid-drive performance

Rides like a normal bike

Frame welded in US

The Scout Pro from HPC is fast e-MTB that looks alot like many standard electric mountain bikes. The difference is that a mid-drive motor with 3000W can be fitted to give this bike a top speed of over 40mph.


  • Throttle and torque sensor combination
  • Frame made and finished in California


  • Clunky battery integration
  • Customisation raises prices

6. HPC Titan Pro

  • UK Flag £6,600

Cn be customised

Alongside the Scout Pro, HPC also produces an extremely fast electric mountain bike with extra wide tires. The Titan Pro, runs incredibly wide 4.8″ tires that help deliver grip and comfort on almost any surface and in any condition.

With the 3000W motor option this bike is capable of speeds of up to 45mph – an exciting prospect when you consider where those extra wide tires will take you!


  • Welded and powder coated in the US
  • Versatility of extra-wide tires


  • Tires will be draggy on tarmac
  • Extra powerful motor adds $

7. Optibike R22 Everest

  • Weight: 93lbs

Long range is its speciality

Top end gearing

Built in the US

Extremely fast electric mountain bikes usually have one major downside – their riding range – that’s the distance they can be ridden between charges.

With the R22 Everest, Optibike set out to make a bike that could theoretically climb the height of the highest mountain in the world. The result is a bike that has a 3250Wh battery and a 300 mile range.


  • Rohloff hub gear is long-lasting
  • Genuinely useful riding range
  • 190Nm motor torque


  • 1 frame size
  • Heavy
