New Crystalyte Buzzing a Bit??   Message List

LOVING It.....was/New Crystalyte Buzzing a Bit??

Hi Gang,
Words just can't describe my excitement over having an electric-human hybrid
bike.

I just have to tell you all how much I flippin' love my E-Cruiser. It is so much
fun to ride an electric bike. It would be tough to attain this speed or distance
unassisted.

Thank you all for helping me get into this cool hobby/sport/fetish hehehe. But
mostly thanks to Danny at Largo Scooters for such a solid product and excellent
sales-support. He's a good guy to deal with.

Cheers,
Dan--Ft. Lauderdale
Strangely enough, nobody notices that my bike is electric as I'm buzzing around
the block at 25mph without pedalling!

Good stuff Dan,

This is also known as the "Shudder" which is fairly common with Crystalyte
and the WE kits. One thing we determined was some controllers were better
"Matched" to the motors than others. This is why some are getting the
slight shudder. Another cause with a similar effect is Voltage Sag as the
packs cannot take the power. Also, bad connectors can cause this as I have
experienced with a friends WE kit.

If it's just a slight shudder and a slight hum then nothing to worry about.
If it gets worse then it's probably one of the above. You may also notice
the shudder go if you feather the throttle. Good indication it could be one
of the above.

Good luck Al,

Richard Papa

The input caps in most cheap controllers are 200 uF at 50v - 100v. The cap I added is 2000 uF at 450v. It was in my junk box and so it was free to me. You can...
