How Reliable Are E Bikes?

I am often asked how reliable are e bikes? and what should we be looking out for to get the best value for money?

It goes without saying you get what you pay for in most cases and there is a reason electric bikes can vary dramatically in price but if you are a commuter for example, then reliability should be one of your top priorities which we will cover here.

Yes there are many cheap options out there under £1000 on the market, but you may want to review your budget after reading this post.


How Reliable Are E Bikes?

How reliable are e bikes

This is all down to the quality of the components, what you are using the bike for, how far you want to ride and for how long .

From personal experience I have a Giant Explore which has done over 2000 km in the last year and it has never let me down – not even a puncture!

This is not a cheap bike (£2800) however the components are excellent such as the shimano Dior gears, Yamaha mid drive Motor and shwalbe tires.

A decent motor from a well respected brand will keep issues to a minimum whether mid-drive or hub based these require little maintenance.

I go out on long rides and use my ebike for commuting 16 miles each way to work so I’m 100% sure that paying a bit more for a bike from a well respected brand has greatly played a part in minimizing any reliability issues.

The plethora of ultra cheap ‘Frankenstein bikes’ you can pick up online can often be a mix of various low quality components from different unknown brands to keep costs down, but ultimately will not stand the test of time so worth weighing this up Vs spending more upfront. – Just my opinion.


How long does the average eBike last?

A decent ebike should last years if you look after it properly, but we are talking about more than just running an occasional rag over it and oiling the chain now and then.

Ebikes will require a proper annual service as components will wear out quicker than on a standard bike depending on what motor you have – usually around the 2000KM mark.


Is it expensive to maintain an ebike?

Recent studies show the average annual cost of maintaining and ebike is around £200 – £250 per year.

Included in these costs are periodic replacement of the key components, for example chains on an electric bike are higher grade hardened steel to cope with the pressure being applied by the motors which will need replacing due to wear. This is usually a good time to change the gear cassettes also.

A recent service of my bike ( mid drive) cost £140 where they replaced both these components, updated the software and re-calibrated the gears and checked brakes etc. Other costs over the year would include a spare inner tube, lubricants and cleaning fluids for day to day maintenance.


How long do electric bike motors last?

You will see lots of debates online about which motor is best – a Hub based geared motor or a Mid drive motor?. The honest answer is both have come a long way in terms of technology and reliability so you really need to weigh up how you will be using the bike to decide on what type of motor would be best suited to you.

There are usually 3 types of motor you will find on an electric bike:

 

Direct Drive Hub Motors

Direct Drives are viewed as older technology also called ‘Speed Motors’ usually located on either the front or rear wheel hubs these motors are quite large and have no internal gearing. Pretty basic in terms of components and rely on bearings to hold out over time.

How reliable are ebikes?

They are maintenance free (sealed) so there isn’t much you can do to elongate their lifespan in terms of actual maintenance, but keeping them less exposed to wet or damp will help preserve the internal components.

Also, they can be prone to overheating over time which can melt the internal components but some claim these motors can go 10,000 miles before needing to be replaced depending on usage but they will drain your battery quickly at high speeds.

I’m on the fence with how reliable these motors really are, after speaking with several ebike technicians they rate them low on the reliability scale – mainly overheating issues.

  • Not so good at climbing hills -Lacks Torque
  • Heavier and adds weight to the bike
  • Rolling Resistance when motor not in use ie coasting
  • Lots of stress on components at high speed
  • Not a very natural riding experience – Mainly used on throttle bikes
  • Pain to repair punctures


Geared Hub Motors:

geared hub motorThese motors are what you will find on most ebikes in the market today and the technology and reliability are improving all the time.

A Geared Hub Motor is a bit more involved compared to the Direct Drive and has a lot more internal moving parts and contains gears within the hub. These motors can calculate the force being applied by the rider and applies the required level of assistance.

Geared  hub motors do give a more natural riding experience Vs the direct drive.

If you are putting in some serious miles each day on your way to work then, or require lots of torque on the hills then performance could start to dwindle over time and the internal gear components may need to be replaced every 3000 – 5000 miles, cheaper versions may need replacing much sooner depending on usage.

 

  • Require lots of battery power at high speeds
  • Pain if you need to fix punctures
  • Under strain at high speeds

 

Mid Drive Motors:

Mid Drive motors are King when it comes to reliability in my opinion and yes they are the most expensive, but in the long term will pay dividends. Mid Drive ebikes ride much like a regular bike when it comes to shifting through the gears.

Mid Drive motors are connected directly to the drive train located at the crank, not only providing a much better weight distribution on the bike but also the power is driven directly from the crank using the gears as the transmission giving a mechanical advantage over hub type motors and a more natural riding experience.

The disadvantages of the mid-drive motor is they put more stress on the gearset and chain, but some manufacturers like Bosch for example are tackling this by adding sensors which ease off the power when shifting through the gears in order to reduce wear on the gearset

Life span of Mid Drive Motors before having to replace can be anywhere between 5000 – 1000 miles depending on usage and various other factors.

 

  • Most expensive
  • Gear cassettes and chain prone to wear

Ebike BatteryHow long do eBike batteries last?

The average lifespan of an ebike battery is usually between 3 – 5 years assuming its from a fairly well respected manufacturer.

You will find over time that the battery range will lose some of its range, but most should be good for up to 1000 charges.

In all cases you need to make sure you do not expose batteries to extreme temperatures (Hot or Cold) and ideally buy models where you can remove the battery from the frame so it can be stored in a sensible temperature of between 10 & 20 degrees (Centigrade) indoors.

Tip: Don’t repeatedly charge the battery from completely flat each time, try to get in the habit of charging after each use which will extend the life span in the longer term.


How Reliable are e bikesWhat are the most reliable eBikes?

Good question, well there are many out there but in my view if you get something from a well respected Manufacturer then you can be pretty sure the set up is correct and components will be of good quality.

Go for a Mid-Drive motor if you can – Yamaha, Bosch, Shimano and Bafang to name a few, are all at the top of their game and their motors are excellent.

Also, take notice of the gearset/ components – are they from a well respected brand – ie Shimano for example for the gears

Price doesn’t always guarantee reliability but if you are going to be doing some serious miles on the bike or using as a daily commuter into work then I you should be setting your budget at £1500 upwards and considering all the above.

  1. I used to have an e Bike for a while, but I was never told it needed to be serviced yearly. I eventually sold it, but it went well and never broke down, so hopefully the next owner didn’t experience any break downs on my account.

    I learned something new again. I see you are supposed to charge the battery after every use and not when it runs out to prolong the life cycle of the battery. I never did that either.

  2. Hey,

    When purchasing an E-bike, one should indeed consider what one is willing/able to spend. Here too the following applies: you get value for money. Someone who will use the bike a lot would better dig a little deeper into their pockets.

    Of course, the total price depends on the components used and their quality. Everything has its price: brakes, tires, battery, gears, and motors.

    A more expensive bicycle means: built from various high-quality components in such a way that the bicycle is much more durable. Such a two-wheeler is certainly worth its price! Of course, the bicycle must be well maintained and receive major maintenance every year.

    In short: to have a really good E-bike, you need to personalize it. Use sustainable materials for this, look at your driving pattern, decide which bike you want to take, etc…

    Nice article!

    With best regards.

  3. Electric bikes are super popular here on the west coast of Florida.  Pedaling a bike all the time in the humidity is really not something that is fun.  I have been wanting to check into getting an ebike, because I think I can still get exercise while using it.  Is that a correct assumption?

    • Hey Learae, yes you can still get a work out on an ebike, in fact some experts say you can actually burn more calories on an electric bike than a regular one due to longer rides and periods of sustained cardio. Good luck with your search and if you need any pointers let me know.

  4. Thanks for all these great details on e-bikes. Our family has considered e-bikes for a while and may purchase them after our move to a new location next year. I prefer to spend a bit more on a higher-quality bike. You have presented a lot of info to help to make an informed decision. Much appreciated.

    • Thanks Joseph, hope the move goes well and let me know if you need any help with choosing your ebikes when the time comes.

  5. What a great write up on e-bikes. I used to have bike but definitely not electrical. I have learned so much about e-bikes from your article that have appealed to me, furthermore I noticed they last only a few years, I assume that’s from daily use going to work and home again. e-bikes are not that different from push-bikes they all need servicing.

    • Hi Yvonne, Glad you liked the article, yes like anything if you are using on a daily basis then e bikes will require regular maintainance but will last for years. parts will need replacing every 2000 miles or so but it all depends on how much you are using the bikes and quality of components etc.

  6. It is amazing how people want a product they buy at a cheap price to outlast the price they paid when that is not the case. So in most cases we get what we paid for so if we want some kind of quality that will last then we may just have to pay.

  7. With the improvement of e-bikes being what it is as the demand for them continues to spike, the best makers in the business have made e-bikes so reliable that anybody wanting to settle for less boggles the mind.

    I recently did an article review on a multitude of e-bikes and found Bianchi is probably the best when it comes to catering to a wide variety of customers who want to go the e-bike route.

    I’m a firm believer you get what you pay for, though. While paying cheap upfront may be a good idea at the time, upkeep costs and performance issues are good enough issues to consider buying models that are of better quality.

    • Hey Millie, thanks for your comments, Bianchi do make some good bikes and the components they use are of high quality also. I’m yet to test one out but like the look of some of their road models.

  8. Thank you for this informative post on the reliability of e-bikes. I’ve often wanted one myself and this is motivating me to look into getting my first one. It’s helpful that you have also listed the reputable sellers of these machines. I’m in the UK so I’ll have a look to see if there is one near me. Thank again.
