Electric Battery Powered Huffy Bicycle using Crystalyte Phoenix Cruiser 7240 kit - 5304 hub motor

Electric assist motorized bicycle using an old 1990's vintage Huffy and an ElectricRider (www.electricrider.com) Crystalyte Phoenix Cruiser 7240 - 5304 front hub motor with 7240 controller, 72 volts from 6 12 volt SLA batteries. The kit had everything to turn my clunker bicycle into a scary fast (42 - 44MPH) and powerful bike. It does some cool burnouts too. What a fun bike! The video was taken in central Florida on a flat road that usually has no traffic. I apologize in advance for the video itself since it is hard to make a video on a BlackBerry holding it in one hand and controlling such a powerful electric bicycle at the same time with the other hand.

How quickly can you stop? How many feet does it take to for you to stop from 30mph? Are you using standard rim based huffy brake shoes?

[idgvdfvdsfhvdf]

@christo930 It takes several seconds (which seems like an eternity) to stop. I upgraded the brakes to bulldog rim brakes with stickier brake pads, but they still stink of burning rubber during a hard stop. The original Huffy brakes collapsed and broke during a panic stop when a truck pulled out in front of me while I was only going about 20MPH.

I don't recommend rim brakes for ebikes, but this old Huffy has no provisions for disc brakes.

BTW, this Huffy can reach 57MPH now at 132v, same motor.

@idgvdfvdsfhvdf That bike is a death trap. Huffy bikes are built really cheaply and they can't take much torque and I wouldn't want to hit a bump on a bike with no suspension and a cheap frame at 57mph. What about the brake caliper unit, did you put a hardened steed bolt to replace the stock one? On my old Huffy there is only 1 bolt on the rear brake unit that connects it to the frame and I serious doubt it could take the stress of trying to stop several hundred pounds moving at 57mph.

@christo930 Part of what you say is true, which is the reason I am building a different ebike.

"Huffy bikes are built really cheaply and they can't take much torque" is highly misleading. Early 90's Huffy bikes were built & welded with US steel and labor. Thus they were heavy & poor for traditional cycling. However, they can take tremendous torque as I have proven again and again. Even after I had a crash that occurred when a truck pulled out in front of me, the frame was unscathed.

@idgvdfvdsfhvdf What did the setup cost you? I am thinking about putting a motor on my bike and it seems that the electric kits are much heavier and much more expensive, while being much quieter and smooth and can accelerate faster. Are their other pros/cons of an electric add-on system? What is your range on your bike?.

[idgvdfvdsfhvdf]

@christo930 The cost adds up quickly. I probably have $1400 total invested in a $30 bicycle.

Advantages include the stealth aspect. Most people don't realize you are electric if you are faux pedaling. They just think you are the best cyclist they've ever seen because they can't hear the motor. Operating electric bikes is much cheaper than gas.

Range is a question I get asked a lot. So, I often ask the person back how far does your car go at full throttle vs. a reasonable speed. No one knows.

[NaltrexoneNotGod]

Wow, that's impressive. I had no idea this technology even existed. 5*

[kenozorro]

Dude!!! u weren't really going that fast without peddaling were you???

[thingjob]

Is this something you have to charge in the garage or does it build a charge by you peddeling?

[VideoQuestEx]

Pretty fast, pretty fast!

[christo930]

@christo930 One other thing, 132 volts can easily break the skin, but can use thinner wires. Why are using such high voltage?

@idgvdfvdsfhvdf Hell yeah you just got me to subcribe! :D
