What is the difference between E-bike batteries? 


MiRider E-bikeRegardless of whether you are buying an E-mountain bike, E-Gravel bike, Electric Hybrid bike or Electric Road bike, battery size is an important consideration to make.

Battery brand and model is also an important consideration. Here at The Cycle Company, we offer E-bikes equipped with batteries from Shimano Steps, Bosch, LG, Bafang, Fazua and more each with its own unique set of pros and cons. 

What are the e-battery options?

Depending on the brand and style of bike this can vary from anywhere between 200W to 700W. This is a huge range and can be a bit overwhelming when first looking for your new Electric Bike. So, it's important to figure out what size battery you need, which can be derived from what and where you would like to ride on your E-Bike. One thing to consider is that the larger the battery size the more weight the battery carries. This has different implications depending on your riding style and type of E-Bike. 

Battery size

Potential Range (this would mean riding on a flat route, using a low level of motor assistance)

400 WH

35 miles

500 WH

45 miles

625 WH

55 miles

750 WH

65 miles

All batteries on the e-bikes we stock can be removed very easily, using a key lock. This means batteries can be charged on or off your e-bike.

What range can I expect?

This is hugely dependant on battery size, what level of motor assistance you ride in, riding location, bike style, bike and rider weight and rider fitness. Saying this we do offer an estimated range in miles for every bike we sell. However, it is an estimate and will vary depending on the aforementioned variables. We don’t have any bikes with batteries lower than 400 WH (Watt Hours).  

What is the difference between an integrated and external battery?

You will see e-bikes with batteries on the pannier rack, on the down tube, or on the seat tube. They can be external, semi integrated and fully integrated. However, where the battery is located doesn’t necessarily affect whether its better or worse. This is still based on the size, the age (whether it has the latest technology) and the brand and you should check all these things before buying a bike. Obviously an integrated battery looks the neatest and some bikes now look almost identical to a
normal bike, the battery is so well hidden.

What battery brand should I choose? 

Not all E-Bike batteries are created equal, they each have their advantages and disadvantages.

Bosch lithium-ion batteries

Bosch lithium-ion batteries are among the most modern on the market. Boasting intelligent battery saving technology to help you get those extra miles. Some brands of e-bike (Kalkhoff for example) offer the potential to add a second battery for really log range rides.

Bafang batteries

Bafang batteries were one of the first on the market and offer better reliability than many think. Combining the latest technology and years of industry know-how, they have developed lightweight, fast-charging, long-life batteries that provide the highest level of efficiency.

Shimano Steps batteries

Shimano Steps batteries keep a greater charge for longer - retaining as much as 60% of max capacity after 1,000 charges. This yields years of reliable battery capacity for the average rider.

Fazua batteries

Fazua batteries get a lithium-ion battery that is at the cutting edge of technology. Fazua's own BMS (Battery Management System) protects the battery from overcharging, overheating, under voltage or short circuits.
