Speed Pedelecs due to their high speed capabilities, are classified as L1e Mopeds in the UK. They cannot legally be used on the public highway unless they are registered (have a number plate) with DVLA, have a minimum of 3rd party road risk insurance, and the rider has either a valid CBT certificate or Moped / Motorcycle entitlement on their driving licence

The Motor
The gearless, direct drive rear motor ensures minimal maintenance and maximum efficient performance. For further information on why rear drive bikes are optimal, please see our article here. Stromer has invested significantly to ensure that while one of the most powerful bikes out there, this is also one of the quietest. Reviewers have repeatedly commented on how near-silent this bike is. Combined with hidden wires, the stealth-like looks of this bike appeal to many.
The Riding Experience
The integrated lights are automatically engaged when braking. A huge 1250 Lumen Supernova M99 Pro gives visibility up front, up to 100 meters. Mount your phone directly into the frame for a second screen / HUD. All wires are hidden into the frame to make the design as streamlined as possible.
The ergonomic ErgonGS1 grips give a comfortable, safe locked grip for long distance riding, followed by hydraulic adjustable brake levers which activate rear lights and regenerative braking when applied.
The Battery
The huge 983Wh battery is one of the largest for any electric bike. It's even charged using pure solar energy from the Stromer facility near Bern!

There are usually two key types of frame. However, certain brands have slightly different names for them so keep your eye out!
Step Over vs Step Through
Sport - (Step Over)
Sport models will usually have a high tube at the top, in front of the seat. This will usually require you to lean the bike slightly to mount your leg “over” the bike. Sometimes bikes will also be called Diamond, or Gents bikes.
Comfort - (Step Through)
Comfort were traditionally known as “Ladies” bicycles, and in some cases this naming convention has carried through. However, all it tends to signify is a lower top tube. By far the majority of electric bikes are step through because they're so easy to get on and off.
Electric bikes come with a wide range of battery sizes. The size of battery has a significant impact on the cost of the bike, and naturally its range.
The smallest, lightest and cheapest battery sizes are around 325Wh. The largest electric bike battery available is currently produced by Stromer and is a whopping 983Wh. For comparison, a Nissan Leaf has a 40kWh, or 40,000Wh battery.
1Wh stands for Watt Hour. So, a 300Wh battery can deliver 100 Watts of power for 3 hours, or 50 Watts of power for 6 hours. How much power (watts) of energy you use, will depend on your ride style and terrain. Most ebikes allow you to choose the level of assistance given to you, which will then vary how many watts you are using.
Range
It is very difficult to accurately predict range for batteries, as the variations in terrain and ride style will vary the range. Using a low-assistance power setting riding around Amsterdam will get more range from the same battery that’s using high-assistance settings riding around North Wales!
Battery ranges should be taken as a guide only, but are usually representative of average usage for the style of bike.
Electric motors can be located in three different places on electric bikes, each giving different ride characteristics. This is a generalised guide to each location of motor, so please be aware that each bike is different and may have custom implementation to overcome.
Hub Mounted - Front / Rear
Mounted directly onto the hub of the wheel, these motors give power directly into the wheel.
Rear
Many of the speed pedelecs have motors mounted onto the rear hub. This gives several benefits such as direct power delivery, giving better handling and high efficiency due to lack of chain energy transmission loss. Weight is better distributed between the battery, rider and motor. It’s a more natural feeling because most traditional bikes also work by powering the rear wheel - only on an ebike you have more help.
Front
A front mounted motor leaves you freely pedalling the rear wheel like a traditional bike, but pulls you along and reduces the amount of effort needed. Front mounted motors are generally considered as a lower budget choice. However an advantage of them is their simplicity in that it’s very easy to change one if needed. Similar to a rear hub motor system if no assistance is selected the bike behaves in the same way as a traditional bike
Mid Mounted
Motors mounted in the center of the bike can give more balance and weight distribution, with the weight lower down and in the middle of the bike.
They tend to have higher Torque ratings because they have indirect power delivery which means they require more energy to achieve the same result as a hubmotor. They are also more complex and less easy to change in the event of an issue.
They are a good solution for electric mountain bikes due to the balance and offer a comparable ride to hub motors for general leisure use.

Where possible we put recommendations in the product descriptions, so keep an eye out! However there are some general rules you can adhere to when choosing a frame size, which you can see in the table below.
| Rider Height | Frame Size | ||
|---|---|---|---|
| cm | Inches | cm | Inches |
| 148 - 158 | 4'10" - 5'2" | 33 - 37 | 13 - 14 |
| 158 - 168 | 5'2" - 5'6" | 37 - 42 | 15 - 16 |
| 168 - 178 | 5'6" - 5'10" | 42 - 50 | 17 - 20 |
| 178 - 185 | 5'10" - 6'1" | 50 - 57 | 20 - 22 |
| 193+ | 6'4"+ | 57+ | 22+ |
Electric bikes have motors located on the crank (mid motor), or wheel hub (front or rear motors), which assist your pedalling. In short, it makes your legs feel more powerful!
You still have to pedal (twist and go are not legal in the UK) but the effort required is greatly reduced thanks to the motor. Hills become easier, and getting away from traffic lights becomes quicker as you can get up to speed far easier.
They are the same as riding a traditional bike, only more fun, pleasant and less tiring!

Batteries can take up to 6 hours to charge from empty, depending on the battery size and charger. However, you won’t need to charge that often and most users are topping up, rather than charging from 0%.
Batteries are removable and can be charged in your office or home. Some high end electric bikes are coming with regenerative braking to capture energy and top up the battery as you ride, further reducing the time between charges.
All of our models have the latest generation lithium ion batteries. You can charge these as often as you like and do not need to be run down before recharging as there i s no memory effect. Important: It is very important to never let an ebike battery discharge completely as this can make the battery unusable. We suggest charging at least once every three months, even if not in use.
There are two limits to speed of electric bikes. These are limited legally, not technologically.
Electric Bikes (EAPC) can provide assistance up to 15.5 mph (25kmh). Once this speed is achieved, the motor will stop assisting and you have to pedal yourself to go faster. This class of electric bicycle can be ridden by anyone over 14 years old and is treated exactly the same as a traditional bicycle.
This is not the case with “Speed Pedelecs”. Capable of 28mph (45kmh) they are able to effectively replace your car for an inner city commute! However, like a car, they require registering with the DVLA and equipped with a number plate.
Yes. The added weight mostly comes from the battery, which can be extremely dense with cells depending on the size. However, when riding the bike you are not going to notice the extra weight because of the motor assistance and quality ebikes are designed to be balanced. They are usually 7 - 10KG heavier than a standard bike.
