How Fast Do Electric Bikes Go

The e-biking community offers a whole range of significant quests. From belt drives, wheels, and internal gears, to voltage and motor power- all these aspects influence most people’s taste on electric bikes.

Thus far, they all come down to one predominant question:

How fast do electric bikes go?

If you are pedaling, you can ride as fast as your pumping ability. However, most e-bikes cease to offer electric-assist when going at 20 miles per hour

Electric bikes in Europe can have a maximum power of 250 watts, allowing for a maximum speed of 25 kmh.

In the US, things are quite different. The Consumer Product Safety Act (CPSA) refers to a "low-speed electric bike" as having a fully operable pedal, a maximum of 750 watts, and a maximum speed of 20 mph 32 kmh.

What Is The Maximum Speed Of An Electric Bike?

When starting off, you may have heard the buzz that electric bikes can go very fast, which is not exactly so true. See, just like bike riders, bicycles also show up in all different sizes, speed, and even comfort levels. One could even say any old-style bike may end up going really fast down a steep heel.

The power assist function will benefit you up to 20 mph (that’s roughly 32 kmh). After that, it’s all up to you and your pumping ability

This is assuming you don’t take the downhill vantage, and you are not even helping peddling .

It is a restriction by law for rider’s safety and persons on foot alike.

Can I Make My Ebike Go Faster?

While the speed of your e-bike is entirely voltage-dependent, you may still stand a chance to go faster than just doing 20. For instance, some premium super-charged e-bikes with available 500-watt motors tend to incorporate an “off-road only” mode.

This allows your bike to reach speeds of 25 mph or even more when you help pedal. Batteries with a higher state of charge provide higher voltages. Therefore, if you want to go faster, staying up to charge is imperative.

But these effects are only applicable in appropriate, outdoor terrains and open areas. It may vary hugely depending on every pack, preserve, and jurisdictions. So be sure to consult the locals before hurtling away at 25 mph.

How Fast Can A 500w E-Bike Go?

Electric bikes with a 500-watts motor will provide assistance to a maximum speed of 20 miles per hour. 

Here, I’m referring only to full throttle, and no pedaling. A well-designed electric bike with a powerful motor can help you attain more power than you actually need with 500 watts or less.

However, if you’re a heavier-set person looking for more speed, higher-powered motors would be a better option.

For instance, if you’re 100 pounds, a 250w motor might be enough for you, but for 220 pounds individuals, a 500w motor may be better. This is because, at top speed, somebody weighing 100 pounds on a 250w motor might hit a speed pretty close to that of a 250 –pound individual on a 500w motor.

How Fast Does A 750w Ebike Go?

Electric bikes with a 750 watts are usually associated with a maximum speed of 20 mph or 32 kmh.

Electric bicycle laws tend to dilute all the fun or at least subside the extreme part of it, but they are crucial for keeping everyone’s security and integrity. 

There are also mid-drive 750-watt e-bikes that can hit about 28 mph. However, most of them are more of a compromise between climbing ability and top speed on flat ground. In other words, a 750w e-bike could go as fast as 28 mph but would fall short climbing hills.

How Fast Can A 1000w Ebike Go?

A 1000w e-bike is powerful and fast. It will comfortably support a 190 pounds and man up any hill with no pedaling easy. It is a great kit and should get you 32 miles per hour (50 kmh) pretty easy.

The only concern is that such e-bikes are often rated at higher speeds and are meant for off the road purposes. Therefore, using them on the road will allude to operating against the law. Such high-powered e-bikes available on the market are not recommended for regular, daily commuting.

How Fast Can A 3000w Ebike Go?

Surprisingly, a 3000w e-bikes can hit speeds of over 50 mph. One downside is that wind resistance becomes an influential factor in speeds over 30 mph.

While 20 miles per hour is said to be safe and sufficient, we’ve heard other cyclists and brands altering their electric bikes to deliver assists up to 40 mph. 

Pedaling effort does not mean as much when you are throttling 3000w e-bike. Remember, top riders put out a max of 700w. So if you’re juicing 3000 watts, don’t expect your pedal input to contribute much to the overall range. Otherwise, unless for off-road purposes, it is unsafe and potentially illegal to make such modifications.

Is 20 Mph Fast On A Bike?

Going at 20 miles per hour may seem like a downright low limit, but it is essentially pretty sufficient. While we recommend that you ride as safely as possible, experienced riders tend to find a few getaways to do it even faster.

It is important to consider that average cyclists are usually going about 12 miles per hour, and most of them hardly exceed that. So you should keep that in mind for safety and regulation purposes. Moreover, in Europe where e-bikes are well established, the maximum speed is 15 mph, meaning we are well excused in the US at 20 mph.

You can easily exceed the prescribed speed of 20mph, but that would be in a condition where the motor is not supporting you. For instance, on a downhill cruise, you definitely can go faster than 20 mph without getting help from the motor.

How Fast Can A 48v Ebike Go?

A 48V electric bike can reach speeds of approximately 20 miles per hour or 32 kmh. But depending on your electric bike, you may be able to hack it and get around speed restrictions and make it go faster.

For instance, with a 48v e-bike that travels about 20 mph at top speed, you can swap on a hub motor to reach speeds closer to 30 mph.

The gearing system and the motor design of an electric bike tend to be more crucial than wattage when it comes to speed. In fact, you may come across 250-watt motors that provide as much assistance as 500 watts or even higher models.

Summary

Obviously, electric bikes have motors, but they are still bicycles and not scooters. So, expecting them to burn up some tarmac like those mysterious motorbikes out there is not feasible. An e-bike is only meant to assist the rider, meaning the motor is never the sole power provider.

That said, if your electric bike meets such speeds and requirements, you can comfortably have it on usual bike trails, streets, and even sidewalks in various jurisdictions, just like a traditional bicycle.
