Top 4 professional things you should know about electric bike maintenance

I encourage learning everything there is to know about the vehicle that you choose to ride/drive from battery function to mechanical operation.

However there are things that require a mechanics expertise so first and foremost what’s gonna take place in this post is what to look for before an every day ride. 

This is not a repair and rebuilding summary. For that I want to acknowledge John Angel and Alvin Bows — these two individuals in the past year have rebuilt, repaired, modded and upgraded an outrageous number of bikes with no signs of stopping. 

While John Angel strictly sticks to Onyx as a preferred choice to warranty/repair/mod. Alvin Bows on the other hand (known as Datshopnyc) has worked on a variety of bikes such as the Sur Ron, Huck, Monday and Onyx. 

They both have provided enough valid evidence that their work is 100% safe for all riders. 

Scroll to the bottom for their contact info.

OK logistics aside let’s get to it. 

First step check your tire pressure. An e-bike will compensate effectively masking the problem of low tire pressure and drain the battery much faster than necessary. 

I created a list of what your tire pressure should be (click here). For best practice look at the side wall of the tire it will state a number next to the letters P.S.I (pounds per square inch). Going above that number will overinflate the tube/tire which is just as dangerous.  

Second step It is important that your brakes are functioning properly. Ebikes are slightly heavier, demanding more from the brakes. 

Check that the brakes are engaging. If your bike is designed with regen braking make sure that it’s functional by turning the bike on, applying the regen brake and inspecting to see that brake lights are activated upon engagement. Followed by inspection, one should check that the cut off to the motor is active and working. 

Third step check battery level. Honestly I noted this as third because the worst thing that happens is your battery is drained and you aren’t able to ride. 

From an electrical point of view making sure that the battery has received a full state of charge is all in creating good habits. When you get home wait an hour before you plug in your bike battery to charge. This is noted specifically by John Angel he has an incredible breakdown of how to properly balance and maintain your battery’s lifecycle. (click here) 

Ideally do this with enough time to make sure you can put your bike to charge depending on what type of charger you have. There is nothing worse than rolling up to a ride only to find out you don’t have enough battery. It will either be a very difficult ride or the ride won’t happen at all.

Fourth step is a bounce and twist also know as a drop and shake check. Yes! Sounds silly I know but sit on the bike, bounce or drop on it. This will help you inspect if there are any strange metallic clicking or clanging noises from the rear end that you should be made aware of before your ride. 

The twist or shake approach is with both hands firmly holding the handle bar steer left/right and push/pull on the handle bars, inspecting that no cables are damaged and that everything is silent and functional.

TIRE PRESSURE/FLAT FIX

The question I get asked about tire pressure is always “what tire pressure should I have?”.

Besides the puncturing of the tire a flat can be caused by: failure of or damage to the valve stem; rubbing of the tire against the road with low pressure, ripping the tire, or separation of tire and rim by collision with another object; excessive wear of the tire tread allowing explosive tire failure or allowing road debris to tear through it.

Some tires, particularly those with a slow leak, and small puncture can be repaired and re-inflated; others, especially those with worn tread, must be replaced.

Those with a slow leak, and small puncture there is a quick fix that can be used on the road. The product is called Flat -A-Fix (click here)

Driving or Riding with a flat tire

When a flat tire occurs, drivers are advised to slow down gradually and pull off the road. Continuing to drive may damage the rim, yes the wheel and hub possibly other components unrepairable damage. Driving with a flat tire, especially at high speeds, may result in a loss of control and an accident.

On a bicycle, a flat tire will compromise handling, as well as increasing rolling resistance.

Proper tire pressure lets your bike roll quickly, ride smoothly, and avoid flats. Narrow tires need more air pressure than wide ones: Road bicycle tires typically require 80 to 130 psi(pounds per square inch); mountain tires, 25 to 35 psi; and hybrid tires 40 to 70 psi. Lets add the new fat bike tires riders use 8 to 25 psi. yes 8 psi for soft conditions (ex:Beach,Snow) and 20-25 psi for urban riding.

The Onyx Motorbikes uses a 2.75 tire. The side wall of the tire indicates 40 psi required. I have gone around and have asked multiple sources as to what they tire pressure they use and what did they find works for them given weight and size of each individual varies. here are my findings.

I weight 168 lb and use 28psi in the rear wheel and 30psi in the front wheel. Currently riding with all original shocks. The rear shocks have been set to the second notch provided making the shock a bit stiffer. Keep in mind at times I have a passenger onboard.

These measurements are based riders with on stock bikes. The changing of temperature due to weather and seasons will also impact tire pressure so be sure to check tire pressure weekly especially if it has been sitting stagnant. Upgraded suspension or battery will change bike weight and handling.

The Pressure should be reduced if an individual is riding on soft conditions (ex:Beach,Snow) by 5-8 psi given that the tire are still a 2.75 (width of tire will determine proper psi) check side wall of tire which states max psi if the psi indicated is 40 psi graph may be applied.

It is much easier to work with the bike elevated off the ground. majority of bike lift need to be bolted into the ground, here is an option that doesn’t and meets the weight requirement to lift the bike. Use the straps for extra measure they are the same ones recommend to secure the battery in its tray for an added measure during larger impacts on the road.
