Breaking Down The Sonic Electric Scooter for Maintenance

Posted on: October 14th, 2014 by Pulse


As far as most forms of transport go, electric scooters are relatively simple to maintain and take care of, the Pulse Sonic especially. There are just a few simple parts that are expected to hold up pretty well with normal use.

However, you find yourself in a situation where you do need to keep checking things out and make sure all the parts are still working, so you can continue to be able to use your scooter safely and smoothly for a long time.

Before every ride, it’s important to do a quick check to make sure everything is working properly. Here’s the main things you need to watch out for with each important part of the scooter, and things you can do to fix what may be broken.

These are the breaks (brakes)

Brakes are vitally important for being able to control the scooter, and should be able to make you stop quickly and smoothly at any time. If your brakes are working, they should, when squeezed, both cut off the motor and stop the rear wheel. Also make sure the breaks are not rubbing together.

If the brakes are hard to squeeze, they are too tight, and you should loosen them by using a 10 mm wrench to rotate the barrel attached to the brake clockwise. On the other hand, if the breaks aren’t actually making the wheel stop, tighten them by rotating counterclockwise.

Charge! (the battery)

The Sonic is charged by 24-volt SLA (sealed lead acid) batteries. Only use the charged that is supplied, and get Pulse to send a new one if it stops giving you a full 40 minutes of riding time, after up to 10 hours of charging. Before charging, make sure the scooter is turned off, by checking the power switch. Plug the charger into the wall.

The LED light will be red as the scooter is charged, and turn green once it’s fully charged. Even if you are unfortunate enough to not get the chance to ride your scooter enough, continue to charge the battery on a monthly basis. Otherwise, your battery will wear out and be unable to be charged at all. Never store the scooter at below freezing temperatures, as this will also permanently damage the battery.

Rolling along (the wheels)

Even conservative riding will wear out the wheels over time, so be sure to look for signs of excessive wear on the wheels. If the wheel is deformed or has flat spots or cracks, it’s time to get some replacements and put the new wheels on. The front wheel is easier to replace. Use two 5 mm hexagonal wrenches on either side of the front axle, turning them together in a counterclockwise direction.

Note where the nuts and bolts connecting the axle are, and keep those together, as you put the new wheel on in the same way, tightening by moving the wrenches in a clockwise direction. The rear wheel, since it’s connected to the motor belt and break, is a little bit more complicated, but still manageable. With the 4 mm hexagonal wrench, remove the bolts to take off the cover. Then, loosen the break cable pinch nut with a 10 mm wrench.

Use a Phillips screwdriver to remove the brake arm bolt, and 13 mm wrenches to loosen to rear wheel axle nuts and washers. Pull the wheel towards the center of the frame, and take time to make sure the belt is not worn as well. Take note of all the rear wheel hardware, and put it back in the same way as you install the replacement wheel in to the frame.

Don’t tighten the axle nuts or the brake arm hardware before checking the washers are securely up against the frame and aligned with each other, tightening them first. Then, reattach the brake cable and reinstall the side covers.

With these basic steps, your scooter should be working well for you for many years.
