Cool Motorcycles and Cool Motors

Now that my riding days are behind me, not by my choosing, I now have to live my motorcycle dreams through my son. So I decided since he has mastered his bicycle skills over the last 2 summers it was time to step up to his first dirt bike. (keeping tradition as my brother and I were riding by age 5).

I didn’t want to frustrate our neighbors with what some would consider loud obnoxious noise (to others like me it is a soothing sound), so instead of going with a traditional 50cc gas dirt bike, I decided to start looking at the quieter electric bikes on the market. (I know, I thought the same thing too….. ELECTRIC??? but it actually is a good alternative for a little one to learn on.)

After a few nights of internet searching, I decided on which particular model/size would be good for teaching my son how to ride and something he could use in our backyard. Negotiations went surprisingly smooth, with the seller AND my wife/mommy, so we picked up the bike last Tuesday. Of course, mother nature decided to “rain” on my son’s (our) parade, so he only got about 3 hours of ride time over the several days that followed.


Once the weather cooperated, I wanted to see how my son (and the bike) would handle different terrain, other than just flat back yard; so we loaded up the truck and headed to grandma’s house because she has “all the cool hills and we can make jumps!” says my son. (JUST what mommy wanted to hear.)

We arrived and I unloaded the bike but before I could have the “safety talk” with him, he was GONE! Riding up the side yard then coming back down and into the backyard, the one with the all the hills. His joy and excitement were short-lived however as the little electric bike, which does great on flat terrain, struggled with the hills and the battery drained pretty quick.

As he went to get off the bike he said that he felt like he burnt his leg, and I knew the one thing it wasn’t from, an exhaust, since the bike doesn’t have an exhaust, it’s electric! After checking over the bike, I did notice the motor housing was quite warm and decided to let it cool down before he could ride again. Well, this just wasn’t going to be an option because he just wanted to ride! (It would have been nice to have one of the our Vortex Tubes or Adjustable Spot Coolers to help speed up the cooling process.)

Vortex Tube    Adjustable Spot Cooler

EXAIR Vortex Tubes can produce temperatures from -50 deg F to 260 F and provide refrigeration up to 10,200 Btu/hr.

EXAIR Adjustable Spot Coolers can produce temperatures from -30 deg F to 70 deg F and can provide refrigeration up to 2,000 Btu/hr.

Both units have no moving parts and are virtually maintenance free.  With that being said, to help the battery from overheating and maintaining a longer electric motor life, either of the EXAIR spot cooling products I mentioned could be positioned to blow cold air over the motor and cool the entire housing due the small size of the motor. Vortex Tubes have been placed right upon large electric motor housings in order to pump cold air directly into the motor itself, with an exhaust port to allow the air to escape. Also, Adjustable Spot Coolers have been used to cool small fractional motors packed inside of a large processing machine.
