As there are a multitude of Electric Bikes with a range of different motor and battery types. I thought we could try and cut through the noise with our helpful Electric bike Guide. Hopefully this will get you more informed and answer some of your questions.
Why would you buy an Awesome E-Bike?
1. Riding an Electric Bike can become a lot more fun.
2. Commuting becomes more practical as you won’t arrive all hot and bothered and it might be quicker on an E Bike.
3. Hills become much easier to ride.
4. Carrying additional weight becomes less of a problem i.e child seats or full panniers etc as the E-Bike takes the strain.
5. Electric Bikes are a great means of personal transport.
6. You can keep up with other riders who are fitter than you.
7. Its a great way to ease you self into cycling and make it more accessible.
8. You may be able to increase you ride distances or durations on an E Bike.
9. Its significantly cheaper than driving a car, getting the train or bus.
E-Mountain bikes have seen the biggest uptake in recent years. Quite simply its about the most fun you can have on a bike. Remember that massive climb before the big downhill that your not that keen on riding up? Well now its not a concern as you fly up it! The best thing you will still have the energy to do it again, or maybe another lap of your favorite route.
You could save £1036 / year just on standing charges, factor in over 14 pence / mile in petrol vs 0.13 pence for an eBike and the saving soon rack up. The average car costs can be rather big with Road tax approx £175, Insurance £806 and MOT approx £55. The costs add up. Compare these with the costs of using an e-bike above and making the change definitely makes sense.
How does an E-Bike Work?
E-Bikes are suprisingly simple to operate, you just pedal the bike and the motor provides assistance at your desired level. You will notice the most benefit when you come to a hill.
Most batteries can usually be charged on or off the bike. Depending on the battery and the amp of your charger they will fully recharge in 3 – 8 hrs. Ranging from a 300Wh to a mammoth 700Wh battery you will have plenty of juice to get you over the hills.
As you pedal the motor measures your output and applies assistance as necessary. The output will change accordingly as the force you put in increases / decreases or you select a different power mode.
If required you can pedal the bike with the motor turned off. Assistance levels range from 50% up to 820%+ assist depending on motor type. Most motors have a walk-assist mode so, if you need to push the bike it makes it lot easier.
E-Bike Motor Systems
There are a variety of electric bike motor system available, the best systems are crank driven. They provide more power and better balance than a hub driven motor. These include:
Bosch Electric Bike Motors

Which electric bike motor system should I buy?
It’s quite possible you are confused about which is the best motor system to buy Bosch, Shimano, Yahama or something else. Its easy to get too focused on the specifications and options available
Our advice is to choose the type of bike that is most suitable for you and not worry to much about which motor brand it has, provided it’s from one of the premium brands already mentioned and you have support available locally should a problem arise. If you have purchased the bike from new from a local bike shop they should have all the diagnostics and dealer support available should anything go wrong.
Types of E-Bike – Which Electric bike is right for me?
There are a number of types of electric bikes available and choosing the right type should be based on the type of riding you plan to do. We have split this into the categories below:
Hybrid, Trekking, Touring and Town Electric Bikes
Hybrid trekking and touring E-Bikes are more suited to road riding, cycle paths and canal paths etc and typically they will come equipped with mudguards, pannier racks, lights and a kickstand. Variants include Step through models, women’s sport models with sloping top tubes and traditional gents model with a conventional top tube.
They make a great option for commuters as you can arrive at work in style without breaking a sweat. They are also great for anyone who just wants to get out and enjoying cycling, choose a more trekking orientated bike and light bridle way and mixed terrain use will become accessible. E-Bikes make a great addition to a motor home as they can be easily carried and give you the freedom to get around after you have pitched up.
Hard Tail Electric Mountain Bikes
Hardtail E-MTBs have front suspension and a rigid rear end. Hardtails make for a very versatile bike as they can be used on any terrain, they still make for a practical commuting, trekking, or town bike with the added option of going off road. Commuters often choose a hardtail as it makes for a practical weekday bike with the added benefit of being able to take it off road at the weekend.
Full Suspension Electric Mountain Bikes
A full suspension E-Bike has front and rear suspension, if you are planning on going off road this the most versatile option.
There are a number of factors to consider including wheel size, tyre size, travel and geometry. For example, if you are not planning on riding very technical off-road then a shorter travel full suspension bike may be more suitable for example 100-140mm travel. Whereas if you are planning on hitting the trail centres or peak district then a longer travel bike may be better 140mm-170mm travel.
The most common wheel sizes are 27.5inch and 29inch wheels including plus size wheels which typically have a 2.8inch tyre. Tyre sizes can range of from around 2 inch to 4.5 inch.
Modern full suspension bikes are very efficient and suitable for even the casual rider, with options to lock out suspension when not required.

Are Electric Bikes Reliable
Electric bikes fitted with the motors and electronics in this article tend to be quite reliable, but occasionally they do have issues. The sort of problems we have seen in our workshop includes head unit failures, battery and motor failures. Fortunately, the failure rate is quite low and most manufacturers offer at least 2 years warranty on the electronics on the bike. When a warranty issue happens we diagnose where the problem is and liaise with the suppliers to source the suitable parts and fit these as part of our after-sales service.
