What is Cadence and what role does it play with my E- bike?
Speed or Power?
It’s all in the gears.
The proper tools makes changing gears easy.
It’s how fast you spin your legs & it effects comfort, range, speed, fun, exercise & endurance. It also keeps those in uniform from thinking too hard about how you manage to go 25 mph without moving your legs.
With all of the information available on E bikes and e- bike conversions I find it puzzling that the topic of selecting gear ratios for our e-bikes is so seldom discussed. Part of this, I’m sure stems from the fact that the majority of today’s E bike conversions are front or rear wheel hub motors and run completely independent of the bikes original drive-train. In addition to a lack of a physical attachment, the subject of cadence, gear ratios, crank sets, freewheels and the 100 year history of everything just mentioned would be large enough to dictate a forum dedicated to that alone. However, whether it’s independent or just to complicated, people, pedals & gears must remain an integrate part of the bicycle’s drive-train. Check out any road bike or mountain bike forum or website and pedal RPM, (cadence) gearing and shifting will be discussed in great detail, yet most electric bike forums rarely discuss the subjects at all. This is, in my opinion an oversight that needs addressed. Regardless of which E-Bike Kit you choose for your conversion project, in order to get the best range and most performance from your newly converted bike, your legs must remain a part of the equation. Since every rider has a certain speed at which they like to spin their legs and we don’t ride in a vacuum we need gears in order to maintain that speed. At this point you might be tempted to say that the hub motor is now doing what the legs and gears were doing before and you would be right. Except that this is not a motorcycle. It’s an electrically assisted bicycle.
That said, I did not pay too much attention to the gearing on my 1st e-bike conversion either. It was on an 1990 Mongoose with a 500 watt Crystalyte hub motor on the front. My gears actually quit working properly after about 6 months from lack of use. I mean aside from needing a place to rest my feet, I’m only going to peddle when I’m climbing a grade or my battery dies. I was far more focused on things like the battery voltage, amps, motor controllers, etc. Perhaps it was the “motor head” in me but It was only after the novelty of the electric motor had worn off and I got into the routine of using my bike for practical transportation that I began to pay attention to practical items like range, cargo capacity, comfort, etc. Let’s face it, in retrospect, the primary reason for electrifying my bike was to increase it’s practicality. NOT taking pedal power into consideration was ,…….. well, very unpractical. Read the rest of this entry

(taken from the “Project Page”)
This is what’s in our driveway at the moment. To demonstrate the full potential of this amazing & amazingly simple form of alternative transportation I use e-bikes almost exclusively for all of my local runs. Since some items are too much for a pair of saddle bags or rear rack I also use the very neat RideKick Trailer on many of my runs. Although it’s designed to turn any bike you own into an e-bike it of course can also be hooked up to your existing e-bike. Since I sometimes have to deliver or pick up bicycles I made a 5th wheel attachment for towing bicycles that simply sets in the bottom of the RideKick Trailer. (lid removed) Then I remove the wheel of the bike being transported a re-bolt the forks to the 5th wheel attachment. The front wheel gets strapped to the side of the bike being towed & sits atop of the now secured pedals. (DON’T BACK-UP) I also use a small ratchet strap & cinch the top of the fork tube to the RideKick Trailer frame where the lid had been. I have to say, this is one slick way to transport an extra bike. Outside of making sure your brakes are up to the task of stopping this load & not backing up, it is one very smooth ride. Oh yeah. An E-Trailer + an E-Bike = very quick acceleration to 20 MPH. Did I invent the worlds very first “Bicycle Tow Dolly”? I doubt it although I have never seen this done. If you have or have seen something similar or interesting, please let me know. I’d be happy to post any of your experiences or photos on the EZgo-Now Web-Site. I’ll be writing more about the RideKick Trailer in a future article. For now you can read NEW RIDEKICK TRAILER That’s Ready To Roll.

Bicycle Tire Pump
I’m sorry about this post but I just couldn’t help myself. I was looking for some clip art on bicycle tools. Specifically the bicycle tire pump on your left when I ran across the bike pictures shown below. These photos are from Stock.xchng.com.

I haven’t done much writing in the last few weeks so I started browsing the Internet for some inspiration. Perhaps something new and original like “The Revenge of the Electric Bike”. Well alas no such luck. However I am continually encouraged and intrigued by the e-bike markets on-going progress and some of the nifty new ideas I so often come across.
On the on-going progress of e-bikes side of things is the time and money some of the major players in the transportation industry are putting into developing e-bike technology. Please don’t mistake this as a belief that the future of the e-bike is in the hands of these captain’s of industry. Quite the contrary. However, it does show that the the e-bike has come a long way from that of a passing curiosity or just another recreational plaything. E-bikes are real transportation and are here to stay.
When companies like Daimler Benz, Volkswagon and Bosch dump hundreds of millions of dollars into the research and development of e-bikes and ebike drive systems we can be sure that e-bikes are more than just a passing fad. Have a look at some of these prototypes and products.

And of course there’s always the “that’s a neat idea” department. Here’s a few with merit.
