5 Ways to get more miles from your EMTB battery

Orange Charger Pro - Shimano EP8 Motor and 500Wh Battery


 "Riding an e-bike that gives more distance, in return for effort put in" 
It's time to lose weight and get fit.

Being in the great outdoors has huge mental health benefits.

 

Electric bikes are a great way to spend more time outdoors, cycling further (Limited to the battery range) and building your fitness while riding trails or bike parks. In a word; they are FUN. 

If you have bad knees or a bad back, you can build some strength bit by bit to go further and join in with your riding buddies. There are now more and more riders on e-bikes. 

EMTB's aren't cheap, starting at £2k, with an average spend of £6k + for carbon frames and the choice of a bigger battery, depending on the use, some people want the smaller battery over a heavy more expensive one. These e-bikes offer a better ride the more you spend, with better equipment to ride the UK trails all year matching the cost of a motorbike. 


Getting 20 miles on a 500 Wh battery works out 4 miles/100 watts. This will depend if you are riding on the road/off road, the number of hills and what power level being used.


Where you ride and how you look after your e-bike will also add to the ongoing maintenance costs. Mud will play havoc on your bike's components and could end up letting you down while out riding if not taken care of. The newer motors are also coming with more torque, made lighter, and give no or little resistance when peddling over the cut-off speed of 15.5mph. 


Maintenance tip: After every ride, inspect your chain for wear, using a chain checker. For 9-speed to 12-speed chains, replace the chain on or before the chain checker reads 0.5%. You will find this is around 300 miles of riding. If you use the motor in full power and have a favorite gear, then a chain and cassette will need to be replaced as a pair. 

I also recommend fitting a steel chainring, made by a UK manufacturer Uberbike, which makes an excellent chainring for e-bikes 


This easy to use chain checker tool is perfect for E-Bike riders to check for wear to the chain & cassette after each ride.


  1. If 1 side drops in the chain needs replacing
  2. Flip over. If 2 sides drop in the chain & cassette need replacing


Note: If you use a favourite gear (high gear/small sprocket in full motor power) it will wear that gear more quickly.


The chain checker is labelled with our customer care line for your convenience. Text or call to be put in contact with your local mechanic.

5 Ways to get more miles from your EMTB battery.

You can buy a bike with a bigger battery, but this makes the bike much heaver than it already is.


Weight-loss is one of those things that really benefits your riding. Every pound you lose, is a pound you don't have to carry up the hill.


The # 1 reason is being over-weight - If you are overweight this is the biggest factor. Buying a more expensive lighter bike is not the answer. It's time to have a fitness plan and stick to it by making it ongoing. Your diet is 85% down to your weight, if you are over 50 years old like me, then you need to focus on what you are eating and stay active to burn the fat and keep it off!

Riding up hills will soon eat up your battery, carrying the extra weight, use your e-bike to get you fitter and healthier and not only to get you outdoors more.

As you get fitter by losing weight you will be able to explore further and get stronger.

Before you do more harm then good. Read:- How to lose weight and get fit cycling


# 2 Train harder - Don't use the full power mode all the time, when on the flat ride in Eco. The newer e-bikes have more adjustments to each mode you use to this type of riding, to get the best life from your battery. 

Once a week ride a non-e-bike, not as much fun but this will help to build strength in your legs. When riding long trails, you will need the legs to power your bike, when you are riding over 15.5 mph, as there will be no assistance from the motor. Be fit off the bike and do compound weight lifting 2 to 3 times a week. 


#3 Ride more in Eco mode - We all like more power, it's fun especially going uphill, and you can keep up with your riding buddies. If you have come from cycling to an e-bike, you will find this much easier, as you will make the best use of the gears and power mode combined with finding the best cadence. Use eco mode especially on hills, it means you won't be going as fast up the hill's and it will take more of your energy, so when you are riding your regulars route start off by riding two hills in eco then progress from there.  If you only have an hour to go cycling, go somewhere reasonably flat and find a speed using eco that you can pace yourself, increasing the length and speed over time. Having a plan and keep it regular each week and you will start to feel the benefits. 


#4 Cleaning and maintenance - Using your bike in full power, in a high gear combined with not cleaning and oiling your chain will put extra load on your motor and drive chain, soon losing the efficiency and more brake downs from lack of maintenance.

The type of tyres (Soft tyres with more grip, means more drag) , tyre pressure and suspension setup, brakes rubbing, all add to more drag and energy from the motor, draining your battery much sooner. Riding more and all year will mean not only cleaning your bike after every ride, but the replacement of  components regularly. Do not use a power wash, as the water will get into the electrics, bearings and will be a costly repair.


#5 Spare battery - Buying an e-bike now comes with the choice of battery size, from 250Wh to 750Wh, having the bigger battery gives you a longer range, but also weighs you down. Carrying a spear battery can mean an extra 3.75 kg's for a 500Wh battery. Some bikes have a place to fit an extra battery on the frame or you will need to carry it securely in your backpack. Losing 1/2 a stone will make up the difference of carrying more weight. 

Efficient Size Battery

Having a max size 500 Wh external or semi-Integrated battery, not only makes the bike lighter but also allows the manufacturer to build or keep an off-road trail riding design. And not those ugly and heavy-looking mass-produced e-Bikes that are built for glossy magazines. It's an efficient size to carry a spare in your backpack or readily available in your campervan to change over. 


The Orange e-Bikes are probably the best e-Bike in the world, for riding the trails in the UK and from a mechanics view, from working on all makes of e-bikes and regular riding with other e-bike buddies. The Orange is a bike that you can repair easily and change over electrical components in an hour or less, with having the basic tools and knowledge.

How To Charge Your Battery, In The Middle Of Nowhere

By having a charging station. The ideal way is to have two batteries, but if you want more time in remote areas and wild camping, then a solar generator is what you need. 

The size required needs to be more than 500 Wh (More than your e-Bike battery) The solar generator can be changed in 3 ways. From your mains, before leaving home, from the 12 volt supply from your car or campervan. Ideally from the leisure battery in your campervan and from a solar panel. Subject to how much sun is available. So, a combination of all 3 ways to charge and keep topped up. 

It's a great way to go for an early ride, and top up your battery while going for lunch or change over to your spare battery and put the other one on charge, ready for the next day. 

A 3-hour drive to the bike park will have your 600 w output solar charger, charged ready.


  • Note that you have an e-bike, that you can easily remove the battery to be charged.
  • There are also e-bike battery range extenders for some makes of e-bikes, that easily be fitted to a bottle cage.
  • Bosch and Shimano offer rapid charges. An average 500 Wh battery will take 3 hours from empty to fully changed with a rapid charger.
  • Looking after your battery, keep the battery indoors and if you don't ride for 3 months keep charged to 80%. Check the manufactures recommendations to your battery.

Exploring further

In less than 2 months I have cycled 350 miles all off-road, I have ordered a spare chain, cassette, derailleur, battery, and a Thule battery backpack, so I can go to Wales and Scotland. (Due to arrive mid-May and I will post details about the backpack)

I would recommend ordering spare parts as items have become difficult to find and it could be 6 months before they all arrive. 

Depending on where you plan on going and for how long, you would also need spare brake pads, tyre, tubes, or sealant. Basic tools to carry on the trail and a set of tools back at the car/van for maintenance and cleaning after each ride, particularly the drive-chain. 


Update: Before, 800 miles the chain, cassette and chainring all needed replacing. I have fitted the SLX cassette, XT chain and the Uberbike steel chainring. I will let you know how this rides and how long it lasts before replacing...........


Do, let me know your thoughts in the comments below, with the cost of e-bikes, are they good for our environment and any tips you have to share or what's you preference in battery size and why?


"Freedom of riding a bike that gives independence in return for effort put in"


While cargo bikes and those who have health issues, a good make of e-Bike with the aftercare support makes sense.

BUT, the e-Bike nonsense - Removing the energy of cycling is introducing problems, from a lifestyle of no movement  - Too much time sitting. We are not here to have an easy life. The flipside is mental depression...


No shortcuts in life, buy a bicycle instead of an e-Bike - Life is not a race.


Cycle further, not faster... Why cycle faster in nature? Ask yourself why do I need an e-Bike? Is it because you are told it's for the environment, or one of your mates in the group now rides one? A well-built bicycle is simple and feels great to ride under your own steam.

How to build a bicycle from a box
By martin wilkins 31 Oct, 2019
It is very important to have your new bicycle built/set-up correctly, for safety reasons, for brakes and gears to work correctly/smoothly and to give you years of enjoyment. Many bicycles are now brought on the Internet and are delivered in a box.
Buying a used bicycle
By martin wilkins 30 Oct, 2019
When looking for a bargain, it is likely these days that you will turn to eBay for a second-hand bike. While there are bargains to be had, when buying a second-hand bike, you need to be careful, because you may have a large repair bill to go with the bargain price. Even if the person is not intending to be dishonest, their idea of the perfect condition may mean clean but worn out. In recent weeks two of our repairers have given out bills of well over £100 to make a bike usable, even though they were described as "good as new".
Chain wear tool
By martin wilkins 30 Oct, 2019
How to look after your chain, check the wear and know how often you should replace before it wears out other components or snaps while riding. The major cause of chain stretch is wearing away of the metal where the rivet rotates inside the bushing and not the side plates of a chain.

Bike out of the box. More than just turning the handle bars and fitting the peddles. Professional assembly of your bicycle purchased online It may be your first or a repeat online purchase, but it is vital your new bicycle is professionally assembled before using it. This is known as a Pre-Delivery Inspection (PDI) that requires proper assembly of your new bike from a box. Parts require checking using a torque wrench and checks must be made to ensure critical components are set up correctly. This will ensure the bike is safe, giving it long-life and for you to have continued enjoyment. The internet is where most people go to for the best deal When you buy your new bike online it will be shipped in a box. A supplier will advise to; "Just turn the handle bars, fit the peddles and you are ready to go" Are you? It is essential that a professional checks your bike first. Checks before dispatch by the supplier, do not guarantee your safety after handling in transit. Consider this very carefully as bicycle accidents can hurt! Tip: When buying your new bicycle factor in the service and maintenance costs. Pose a real danger to yourself and others Doing it yourself means you need the correct tools. A torque wrench or know the feel for how tight the bar stem/bars, the steering, peddles and seat post bolts should be. Know how to set up the ride potion, to know if a component is functioning correctly, requires adjustment or has been damaged when being delivered. Cyclists call us when it goes wrong Quit often a customer brings a new bike in for repair they just brought online, saying the gears are not working correctly. On a closer inspection, the bicycle shows up more issues; misalignment of critical components, brakes rubbing, rounded of hex key bolt heads, loose steering and even the wrong size bike. Our Technicians are always on-hand to get you back on the road, as soon as possible in a safe manor. The way we can get involved with a bike that has not been PDI'd by a professional, means carrying out a full PDI to make sure the bike is safe to be used on public roads after being seen by one of our Cycle Technicians. Part of the PDI processes is the hand over, making sure the rider knows how to use the gears, when to check the tyre pressure and to what pressure, how often the chain needs oiling/cleaning and when the bike requires servicing. For ebikes; advice is given on charging and storing the battery for reliability and long-life. Or this can mean an expensive non-warren replacement, if not maintained as manufactures recommendations. 'Good Practice' The bike trade also recommends a first service at 30 days from date of purchase, to make sure everything is running smoothly and make miner adjustments of brakes and gears, plus check the steering, wheels, crank for fitment and correct operation. Its even more essential that ebikes are inspected more often. Particular the brakes and chain for wear. ebikes are much heavier on the brakes and drive-chain and require replacing parts more often, before wearing other associated components or complete failure, resulting in a expensive overhaul to bring the bike back to good working order. This Is What Cyclists Are Saying When They Contact us: "The pedal come out! Its only 6 weeks old." "Had gear issues for ages, had a new derailleur fitted few weeks ago, still felt dodgy, bikes only 3 months old, just bought new shifter and cable and need them fitting and gears sorting, new headset, and rear wheel bearings looking at" "Bike has got stuck in highest gear. Thought the suspension lever was the gear lever. Never heard of that before"
