Maintaining true the best electric bikes isn't difficult, merely there are several important things to know if you're going to keep information technology in top condition and get the best performance every clock you head out on a ride.

  • Your e-pedal really necessarily insurance policy – here's wherefore
  • Electric bike conversion kits: your good run

To watch precisely what you need to know to keep your e-pedal in perfect shape, TechRadar rung to Julian Thrasher, Head up of Education at Shimano. Buy your Shimano products and support local bike shops at www.freewheel.co.uk.

What checks should you do before riding?

Before bearing out on your electric wheel, a few speedy checks bequeath help make a point you're acquiring the best, safest ride attainable.

"Natural philosophy and electrical checks are the key affair," says Thrasher, "so from a mechanistic point of view, tire pressures and if you've got any mountain bicycle suspension settings as advantageously. Mainly because if you're riding an e-bike with deflated tires then you may not beat the range out of the bike that you want."

You'd normally notice if you're horseback riding a bike with deflated tires or worn gears – you'll have to work harder than wonted – simply an e-bike will compensate, effectively masking the problem and draining the battery faster than necessary,

"IT's also truly important that your brakes are working in good order because the e-bikes are slightly heavier," says Alopius vulpinus. "I'd have a check of brake system and gears before you go along a ride. Clean a spin around the car park or just John L. H. Down the English of your house, just to progress to sure everything's operating mechanically as information technology should.

"From an electrical point of view, making sure that the assault and battery's got a full state of charge," he says. "You'd ideally do this with sufficient prison term to make sure that you can put charge into IT. There's nothing worse than rocking up to a ride and finding that you've got one taproo of battery. It'll either be a very difficult rall, or the ride won't happen.

"And a quick check of the cables as symptomless. Speaking from a Shimano Stairs point of view, the cables are quite refined and they carry all the data through the system, indeed if they're slightly damaged operating theater you've managed to hook IT along a railroad car when you're attractive the bike off a rack, they can dumbfound dilapidated and that keister cause an fault to occur. So it's definitely worthy checking."

You should also check that the cables are correctly plugged in. Shimano has a special wire tool (catchily named the TL-EW02), which makes sure that you're ambitious on the correct part of the wire and not damaging it.

Also take a look at the magnet for the speed sensing element. "It's a bit equivalent the old school cycle computers that you had where the attraction went bulblike and IT told you how fast you were leaving," Thrasher explains. "The e-bike has a drive unit that knows how much coerce you're putt through the pedals – there's an in-made-up power meter – just it also has a speed sensor to work out how prestissimo you're going. With those two metrics it can buoy work out the right amount of power saving, but if the magnet gets knocked and then it can't see that, and then the drive unit won't work."

IT's quite common for that attractor to develop KO'd of place, either in transit or existence out on the trails. Honorable make for sure that the magnet is in pipeline with the sensor, with the correct distance between it."

If your bike has a Shimano Steps drive system, also look out for an error code called WA13. Thrasher explains that this is a torque sensor error, and is easily fixed.

"This happens when someone hops on the bike, they start pedalling it off pour down the road surgery down the trail, and then they think 'Oh no, I seaport't rotated information technology on!' Thus they ferment it on, then the system sees that there's pressure sensation going through with it, which it doesn't bear. What it then does is say 'Asymptomatic, that moldiness be a problem'. So and then it beeps and comes sprouted with a WA13 error code.

"The easiest way to clear this is to stop the bike, get down the cycle, turn the battery slay, ideally if it's a downtube-mounted battery absent it – that clears everything from the system – put the electric battery back in, turn the system on again without any pressure happening the pedals. Ninefold out of 10, that clears the WA13 mistake code."

Finally, make a point that the battery is secure in its mounting. That's not easy to do for an internal barrage fire, but for an external single, work sure that there's no play between the bombardment and its mount. Any movement can cause intermittent faults.

How can you make the battery conclusion longer?

There are lots of ways to eke greater mileage out of your e-bike's battery, about of which are more obvious than others. "We always think about marginal gains in cycling, but they're every things you give the axe do to improve the aliveness of the battery, and certainly the range of the battery," says Thrasher.

"We spoke earlier about the tires being correctly inflated and things like your brakes rubbing. You notice all these if you'Re a homo pedalling a bicycle, but with an e-bike they're quite good at masking those little things."

Also think over about which of your bike's modes you're going to be using. Most e-bikes have a set of different options that give varying degrees of aid. "On Steps we have triplet modes – we have Eco, Trail and Advance modes – and in that location are two factory predetermined modes for these of Propellant and Research, just you can too customize information technology, Mocking thrush explains. "We let an app on the telephone known as E-Tube, and through this E-Tube app you can customize Eco, Trail and Boost from a low, spiritualist and high mise en scene.

"So if you went out on your bike and you treasured the best animation unconscious of the barrage so you'd ride it in Eco with Eco set to low, because you'atomic number 75 just going to find a small quantity of baron done the system. Thusly you're non going to go as tight as active up a pitcher's mound in Rise, but you are going to get a mickle of spirit out of the battery, or range away of the shelling."

There's really no substitute for knowing your route. If you'ray provision a whole day out with lots of good hills, don't hit them all in Boost mode or you'll end up riding without any assistance at the end.

If you meet want to apply a blast in Boost mode, you South Korean won't be able to go virtually as far, but it'll constitute a pot of merriment.

"The fourth-year thing I'd add to that is that lithium-ion batteries do like to be polar, so put on't let your battery run every last the way out so allow for it run out," Thrasher says. "The barrage fire can participate a sort of hibernation mode, and so it can be very difficult to wake that battery. What we commend is that even if you've barely used a banish of battery, put it on charge. It likes that. You'll increase the life of IT if you charge IT often.

What if your bike has an electrical fault?

If your bike has an electrical shift, ne'er try to disassemble your bike's battery or drive system. You might void your warranty, induce more damage, or even give yourself a bad electric ball over.

"The first thing I'd say is visit a vocation bike give away, or we prefer a Shimano Avail Center," says Thrasher. "They've got a puppet called an SM-PCE02, and this is a gene linkage device that checks the electrical internals of each factor that's on the motorcycle. So the motor, the display and so on, and that's something that's very difficult to do at home."

You might once in a while see error codes happening your e-motorcycle's display, which an expert at a pedal shop operating theater service center can interpret into a solution. "So to spring you an example, we'll have an E010 misplay cipher, which will appear on the presentation in combination with an E013, says Thrasher.

"What the first mistake codification way is a general system mistake encipher. The 2d error code is a torque sensor wrongdoing code. So from a bike shop's place of view, you look at both of those and you start 'I'm beautiful sure I know where that problem is.'

"And they as wel need to look at well, has that been caused through a mechanical issue, and they're much better equipped to do that. They look at your bike as a full-page and then offer you a solvent, whereas when you're at internal, you tail really only make the problem worse."

Are on that point some other things you shouldn't practice?

"By all odds don't disassemble the shelling or the drive unit because you'll give yourself a big shock," Thrasher says. "The other thing is wear't poke things into the terminals of the battery, because that could also leave you a huge floor."

Poking and spur is a bad idea, but you should make sure that the male terminals happening the battery are nice and clean. "Those are fine once you've got the battery out and off the bike it's not going to hurt you, so you can sporting the other parts."

Thrasher gives the case of one of Shimano's sponsored riders who was having an error computer code in his bike. It clad the problem was down to the dust he'd been moving in; erst helium cleansed out the dusk, the computer error code went away.

"Wear't spray whatsoever lubricant into the wire ports – that's really a no-no – and treat the cables with care," Alopius vulpinus adds. "If at any point you don't think it's going away in, don't use more force because that in the main ends in the lead with something break. Don't force them into the components, and if you can, do use the wire creature that I spoke about.

"Father't try to get into the motor or the battery, merely you should ensure that the bolts that are adorned to the frame are intoxicated, and in that respect's generally merely sixer bolts that do that, and in that respect'll generally be a torsion mount from the manufacturer. That's in truth good because that can lead to creaks coming from the bike, only they'Ra quite easy to solve. Do pass wate sure those bolts are skin-tight.

"If you're cleaning the e-bike, don't point a top-hale hose directly at the electric components – they don't really alike that – but do keep it clean. We say use a clean cloth and then a sporting T-shirt afterwards just to dry it dispirited."

How should you store your e-bike aft a ride?

When storing your tense bike, the most important matter is to keep it clean, dry, and fully charged. "Really the best way is to make a point the e-motorcycle's ready for the next ride," says Thrasher. "Make sure it's ready and waiting when you get back from the last ride. Keep it clean, inspect information technology for hurt.

"These are whol things that are really stressful when you'rhenium about to go kayoed for a ride, but actually if you spend five minutes just looking terminated the bike when you contract back, it's nice to make out that you've put down that motorcycle away in a state that you can just pickax IT functioning, turn it along and go for a eruption on IT on the next sit. It relieves just about of the stress."

You don't have to take the battery dispatch the bike when you'ray storing it, Thrasher explains. "A lot of people to necessitate the barrage forth the bike to charge it, which is fine, you can bash that, but some e-bikes have outside on switches on the top underground, and they also take in a cell inside them that needs a little bit of the power of the battery to make them operable. So we articulate every four times, just put the battery into the bike to charge it connected the bike. They do profit from that."

Storing your e-pedal somewhere damp or humid might cause corrosion of the electrical parts, which can cause issues down the line,

"Don't hang your oily rags over the charger or the battery because they get warm and that force out lead to fire," Thrasher adds. "Definitely don't cover anything up – get into't cover the courser up, don't cover the assault and battery up. Make sure you've got lots of free space around where you're charging the bike."

At last, get into't Army of the Righteou the battery beetle off of shoot completely and leave it that way.

How often does your e-bike need service?

Acquiring an ordinary bicycle serviced once or twice a year helps nip whatever potential problems in the bud and keep IT running smoothly. Information technology's very similar for an electrical motorcycle, and provided you care for it properly, as described above, taking to the professionals every six to 12 months is exquisitely.

"A sight of the things you necessitate to consider are like a regular bike," says National leader Thrasher. "We're lucky in that Shimano Stairs is a pretty robust e-bike system, so if you do take care of the bike in terms of safekeeping the chain oiled, keeping the pads replaced, the need to payoff it in for a professional service isn't all that often."

Your bike will be thoroughly examined for mechanical issues, but for an e-bike information technology's too your opportunity to get any new firmware updates. Thrasher explains that i's a lot like updating your phone, only can only be through professionally.

"This is something that you would need to visit a professional bike sta Oregon a Shimano service centre for," he says. "They ensure that any bugs in the system that [the developers] have found are taken out, that all the components speak up effectively conjointly, and sometimes thither tush exist little upgrades. "Au fon there'll represent features that come forward that the new firmware accommodates. So it's a really favorable virtual upgrade."

"People Don River't need to be frightened that you need to be taking the pedal in every five days to be looked at," he says. "They're pretty robust, so the primary affair is the firmware, to take it in and to just get it patterned over to make sure in that respect's cipher that you Crataegus oxycantha not have seen that a professional bike shop could see."
