The e-bike craze has officially hit the USA, and tons of performance e-bikes capable of extreme speeds are swarming the market. These bikes do, of course, have to abide by government regulations that limit their speed depending on what class they fall under.

So, if you're purchasing an e-bike, ensure it meets your local laws and regulations. Many manufacturers ship your e-bike with a restricted top speed to abide by local laws. But they allow you to unlock the bike's full speed through certain modes that can be used in special settings.

Let's explore the fastest e-bikes available in the US!

1. Hi Power Cycles Revolution XX

The HPC Revolution XX is the type of e-bike you look at and immediately begin to wonder if e-bikes are getting slightly out of hand. The Revolution XX is the world's fastest e-bike, with a top speed of 74 miles per hour (tested on a dry lake bed), thanks to an output of 10,000 watts, or 13.4 horsepower. The crazy part is that you can even pedal along at that speed—yikes!

The fact that this e-bike can achieve 74 mph proves that e-bike manufacturers have lost their collective minds. Quietly, this might start an e-bike performance war that could rival the competition going on between the bonkers-fast Tesla's Model S Plaid and the Lucid Air super EV sedan. The funny thing is that the Revolution XX that will ship to you in the States complies with Class 2 regulations, which means its top speed is limited to 20 mph. Only with the limited top speed could you expect to achieve the maximum claimed range of almost 100 miles.

You can then choose to activate the off-road mode wherever it's legal to do so, which gives you full power. Only 20 of these super e-bikes will be built, so if you want one, hurry up and order one. The price is an eye-watering $20,000. One thing is for sure: if you want the absolute fastest e-bike out there, your wallet will not go unscathed.

2. Hi Power Cycles Revolution X

The Revolution X is a $13,000 e-bike with a top speed of 65 miles per hour (if you opt for the 8,000-watt model, which adds $2,000 to the base price). If you need to prioritize torque over top speed, you can order your Revolution X with the Torque motor, which is better for climbing hills and going off-road. You can choose from three battery pack sizes: 1.3 kWh that's good for 55 miles of range, 1.8 kWh that pushes range up to 80 miles, and the top 2.4 kWh pack that will take the bike up to 100 miles on one charge.

If you want the ultimate top-speed machine, you can go for the Speed motor, which emphasizes outright speed over hill-climbing ability. The great thing is that choosing whichever motor fits your needs best is a no-cost option. Hi Power Cycles (HPC) allows you to customize your Revolution X as much as you want; you can even choose any color you want for the wheels and body if you go for the Stage 2 option, which will set you back $700.

The HPC Revolution X isn't a cheap e-bike by any stretch of the imagination, but if you want a high-quality e-bike capable of achieving amazing speeds, the Revolution X is hard to beat.

3. Stealth Electric Bikes B-52

The Stealth B-52 e-bike doesn't just have an extremely cool name; it's also very fast—this bike can accelerate to a top speed of 50 mph. The B-52 features a 2.5 kWh battery that provides up to 43 miles of range, and it can be fully recharged from empty in 3 hours.

This ultra-fast e-bike also features a six-speed transmission, so it's definitely useful in many scenarios. The e-bike itself features a futuristic design that's sure to capture many looks wherever you go. Honestly, like many of these super powerful e-bikes, it looks more like a motocross bike with pedals attached to it, but the look works very well.

Another cool visual touch is the placement of the company's logo, which adorns the side of the B-52 in dramatic fashion, making this e-bike instantly recognizable as a Stealth product.

4. Delfast Top 3.0i

The Top 3.0i will be shipped to the buyer in legal mode, essentially making it a Class 2 e-bike limited to 20 mph. As crazy-fast as this bike is, it's even crazier to think about riding around on a bike that looks this aggressive while being restricted to a 20 mph top speed. With the limiter in place, fast cyclists on traditional bikes can speed past your restricted Delfast bike. Thankfully, you can unlock the bike's 50 mph top speed if you're going off-road by entering Unlimited Mode. Unlimited Mode gives you access to the Top 3.0i's full power.

The Delfast Top 3.0i is another e-bike that blurs the lines between a full-on electric motorcycle and an e-bike. But Delfast markets the Top 3.0i as an e-bike, even though its appearance is so radical. This e-bike wouldn't look out of place in a Blade Runner movie, especially in the hands of one of the bad guys. It looks like a futuristic motocross bike, but without any unwanted noise because it's fully electric.

The 50 mph top speed makes the Top 3.0i a formidable e-bike, guaranteeing no other cyclists on traditional bicycles will simply pedal right past you. The top speed is especially amazing when you consider that the range of this monstrous e-bike is an astonishing 200 miles thanks to its large 3.5 kWh battery. Of course, it doesn't beat the Optibike's 300 miles of range, but considering the Delfast Top 3.0i can smoke the Everest in terms of top speed, nobody will be complaining too much.

Another great thing about the Delfast Top 3.0i is that the official website carries replacement motors (attached to a new wheel and tire combo) and replacement batteries.

5. Optibike R22 Everest

The Optibike R22 Everest is an impressive e-bike. It's very fast, with a top speed of 36 mph, which puts it in rarified air in terms of e-bikes. It's also one of the few e-bikes that can handle pretty much anything you can throw at it. There isn't much that will hinder the R22's progress, whose powerful electric motor serves up to 190 Nm (140 lb-ft) of torque. But there's so much more to it.

The R22 Everest offers up to 300 miles of range, which means it can go toe to toe with many electric cars and is among the e-bikes with the longest range. The reason for this extended range is the battery, which has a capacity of 3.26 kWh.

The Optibike Everest R22 is the perfect example of an e-bike that can easily serve as your daily driver. The fact that it's equipped with a throttle and an enormous battery pack makes it an ideal companion for urban driving, even for longer commutes. This is especially true if you're navigating a city with lots of hills, like some in California.

Using the R22 as your daily urban runabout would definitely be a breeze thanks to its 36 mph top speed. The great thing about the R22 Everest is that you'll arrive quickly at work sweat-free thanks to the e-bike's throttle (so you don't have to pedal at all), and you probably won't have to charge it for the entire week thanks to the huge battery capacity.

Performance E-Bikes Offer Impressive Versatility

It will be interesting to see how manufacturers try to top the performance of the current crop of e-bikes in the future. The models described above are all absolute monsters and feature incredible ranges to go along with their earth-shattering performance, making for versatile rides that offer speed and everyday usability. Hopefully regulations don't start to sap the fun out of e-bikes in the future because it will be great to witness how far e-bike performance can be pushed.
