As OWT pointed out, when they sell the eZee with a 20" wheel, the motor is wound differently so that the rpms are higher. If I can cruise at 20 mph (32 kph) for extended periods while pedaling, I will be a happy man. My one-way commute is 20 miles (32 kilometers). I used to be able to cruise at 15 to 16 mph (24 to 26 kph) on my Gold Rush and it would take me 1 hour and thirty or forty minutes to get to work. The Gold Rush has a full fairing and is very light by recumbent standards. It's the production model of the first bicycle to go over 65 mph (105 kph).

Yes, I did. If you purchase it with the eZee motor, it is only an extra US$110 and from the information available on this forum, it seemed to be an invaluable asset, especially its ability to protect against overtaxing the motor and battery.DahonElectric wrote:Did you get a Cycle Analyst with it?
I am one of those few people you speak of. If I ever need to lock my Gold Rush (which is very, very rare), I carry that very same monster lock and chain you speak of. And I also carry a motorcycle cover. When it is locked up and covered, it resembles a covered and locked motorcycle. All you can see is the cover and a monster chain and lock peeking out from under the cover and locked to a lighting pole or traffic light or some other large metallic object. I'm sure I'll use the same system for the new e-bike (for those rare instances where I need to lock the bike).DahonElectric wrote:Do you ever wonder why few people carry the heavy Kryptonite New York lock and chain together (combined weight is similar to the eZee) ...?
Well, my first day of extended riding was a splendid success! I rode the 20 miles (32 km) to work in about 1 hour and 20 minutes averaging almost 17 mph (27 kph). I checked the axle and battery temperatures several times. I could discern no temperature increase in the battery. The axle was just slightly above my skin temperature -- barely able to notice a difference. Very cool! (No pun intended.) I only used a bit over 8 amp-hours to travel the 20 miles.dogman wrote:For long rides, like the 20 miles you speak of, I can't recomend monitoring temperature strongly enough, regardless of climate if there is any long hills to climb.
I won't be getting rid of my car, either -- at least not any time soon. But I do hope to reduce my car mileage by at least half, hopefully more. I am also a registered financial representative (a.k.a. stockbroker) and I just can't ride up on my electric bike to most of my clients. (A few won't mind, to be sure.)dogman wrote:I'm sure your bike is sound and ready for a daily 20 mile pounding, so let er rip and enjoy! I haven't gotten rid of my car, but I've cut it's yearly mileage in half. The days I drive now are only because its so hard to carry 200 pounds of lumber or 1000 pounds of cement on a bike.
Just got back! And your admonition regarding spying the available scenery was taken very much to heart. Do come visit soon and be sure to PM me when you are in town -- would be happy to get together.dogman wrote:Take a cruise down the PB boardwalk for me, and don't spare ogling the thongs.

The American economy will have a difficult time adjusting to the loss of the outsized profits that come from the American public owning and operating cars. But adjust we must. We have no choice.

It only happened once but it made me feel like crap. I took the damn car in to get my gear shift fixed and they ended up fixing my clutch which WASN'T EVEN BROKEN. I was so mad that I said the hell with this stupid car. I got me an electric bike.
So far, my new mistress has been serving me well for short distances. The longest we've been together has been less than 9 miles (15 km). She is a blast to ride. I have been pedaling to get up to around 10 mph (16 kph) and then using the motor to get up to around 20 mph (32 kph) at wide-open-throttle. When getting home, I can not discern any significant change in temperature in either the battery nor the motor. (I don't have a thermometer; I am just using my sense of touch.) Happily, I consistently seem to be getting a bit less than 3 miles (5 km) for every 1 amp-hour I use. Since my commute is 20 miles (32 km), I am certain that I will be able to easily make it to work in the morning. My first commute will occur this Friday. My mistress and I are ready for that first long trip together.
Here's my concern: The eZee motor is rated at 400 watts and at wide-open-throttle, the Cycle Analyst reports that we are almost always below that amount. However, when accelerating up to maximum speed or ascending a hill, it is typical to reach upwards of 700 watts. I have the maximum amps set to 15 so it should only be hitting 600 or so but there seems to be a lag before the Cycle Analyst instructs the controller to back down. From reading posts here, it seems that this is typical and not a cause for alarm. Is this correct?
As always, many thanks to everyone here for sharing all your valuable experience and advice.

My 9C was initially set to 20A max (20A controller) and was getting like 685W to 580W during acceleration, climbing and fighting a head wind. After setting it down to 10A, it's averaging around 350W for a 500W motor, but the accelerating is slower, hill climbing maxed out at 25kph as opposed to 32kph and battery endurance has increased. Since you own an eZee motor, why not try out using the cruise control function of the Cycle Analyst?
