Now that I've purchased the eGO Classic, I was rummaging around and took another look at my poor forgotten Amplifier A7 scooter. Back about a year and a half ago, I was riding it to the Metro and hit a huge pothole. The county was rebuilding the sidewalk and redoing the handicap ramp at an intersection. I didn't see that there was a huge gap between the street and the curb so went through that 5 inch gap and broke the plastic rear axle of the A7. What a sad day that was. I loved the A7 and haven't been able to find a replacement axle for it. The A7's axle is unique in that it contains both the drive belt cogs on one side, but also a smallish disk brake rotor on the other side. 

Here's a picture of the defunct brushes that needed to be replaced in my eGo scooter. Next to it on the right is the new brush. A very small part to have such a big impact. It took almost a complete take-apart of the scooter to get to it but the scooter was extremely well made and thought out. It only took 8 bolts to take the motor out and to replace the brushes.

As you can see, the burnt out one on the left looks kind of scorched and the springs are completely shot. They still have lots of material left in the brush as you may be able to see from the lines on the side of the brush, but it wasn't up to the job. The scooter had been used for about 3 years and they lived in a hilly area in Washington, DC so it probably had to be used pretty hard.

Oh, BTW, the brushes only cost $20! Thanks to AeroWhatt, eGo scooter Guru supreme!

I was able to pull apart the eGo scooter and clean up the inside as well as replace the brushes in the motor. They were pretty much gone and they were responsible for the slowness and lack of power in the scooter. The eGo is supposed to have a 1,500 Watt motor or the equivalent of almost 2 horsepower! It felt as if I was getting maybe half of that. Now with the new brushes, I am getting full speed as well as full hill climbing power now! WooHoo!

I've put some photos of the scooter being rebuilt up:
