Although Decathlon bikes do seems to be a little pricier than other bike manufacturers this is because they make their bikes with very high-quality components. 

What Is a Hybrid E-Bike?

A hybrid e-bike is a type of electric bike which is good for road riding as well as mountain biking, instead of having extra weight due to thick mountain bike tyres and suspension, the hybrid design compromises so as it can have a lighter weight difference for commuting too.

Main Features Of The Riverside 500 Decathlon E-Bike

So as you can have an easier browsing experience when it comes to looking at the Riverside 500, we have broken down the specs of this Decathlon electric bikes model and reviewed the individual components in detail. 

Motor Power & Battery

The Riverside 500 decathlon electric bike features a 250W motor, meaning it's legal to use as a regular touring bike or road bike in the UK, this is also sufficient power for most people who want a decent hybrid bike. 

In terms of the battery capacity, this hybrid bike has a range of up to 50 miles, but this does depend on the electric assistance you are using and whether or not you are using your electric bike for road use or mountain bike terrain.

Gearing & Brakes 

For gears, the Riverside 500 model uses a 1x8 speed set-up with a B'Twin branded gear shifter which allows for a smooth experience when changing gears and can be accessed by the handlebars on the bike for quick changes. 

This Riverside 500 hybrid bike is also equipped with Tektro TKD 160 mm hydraulic disc brakes for reliable stopping power on even technical terrains, making the bike a more pleasant experience to ride.

Although we think that these twin bikes gears are pretty basic and the mechanical disc brakes are fairly entry-level, the brake power is not too bad for the bike, but may not suit serious watery mountain terrain or rocky mountain terrain. 

Suspension & Frame 

The suspension on the twin bikes design uses a Suntour NCX SF17 lockout front fork on the alloy frame which is adjustable and has 63mm of travel for more comfort on rocky terrains. 

These forks are great for the bikes price range and you shouldn't need anything more heavy-duty for a hybrid bike. 

Frame-wise, the Decathlon bike has a couple of different weights depending on the size of the bike that you get, the bike however in a large frame size weighs 22kg without pedals.

Its design is made from light weight alloy material and is positioned so as the user will be sitting in an upright position, the frame also has a lifetime warranty which makes the whole Decathlon bike much more reliable. 

Wheels & Tyres 

Wheel size of this hybrid bike has a measurement of 28-inches which is similar to most common electric mountain bikes, the tyres of this bike additionally have double-walled alloy rims for durability and the hybrid tyres have fairly good puncture resistance. 

These wheels and tyres overall allow the hybrid bike to handle technical terrains quite well in addition to flat terrains.


One of the features we like about this Decathlon hybrid bike has to be its accessories included which allows you to avoid buying extra items.

Some accessories which are worth pointing out are the high comfort B'Twin designed saddle and B'Twin pedals, front and rear mudguards as well as a rear rack and bottle holder are included too among the items.

Should I Buy This Decathlon Electric Bike? 

If you wondering whether or not this Decathlon bike is for you, then you need to consider what you will most likely be using it for. 

Although this e-bike is a hybrid model and can technically be used for mountain biking as well as commuting we would not recommend it for very rough adventures and class it as more of a leisure bike.

Overall, if you have a bigger budget and want a reliable hybrid bike that can cope with multiple terrains, has a decent amount of torque power and great levels of assistance, then this Decathlon Riverside 500 model could be great for you. 

However, this bike has a fair few electrical issues reported since it came out, the B'Twin bike would also not be great for using on serious off-road terrain due to its low battery capacity, you might be better off checking out the Rockrider model if you're after more of a durable model. 

How Expensive Is The Riverside 500 E-Bike?

The Riverside 500 E-Bike is one of the most expensive bikes in the Decathlon range and has a current price of over £1000.
