I've ordered the Cyclone 500 watt

I’ve been considering my next electric bike project for a long time now (I have a gohub now). I’ve been wanting a second electric bike thinking that maybe the wife and I can zip around together without one of us (usually me) being out of breath. For those that have or are thinking about another ebike project, you probably kind of know what I’m going through. Do I build a new bike to be (usually can choose only one of the following) faster, lighter, cooler looking or maybe with just longer range? Balancing performance with cost you can live with is tough but it’s also what makes the project fun. Take for example, deciding if you should find a kit that fits the bike or get a bike that fits the kit best.

For the longest time I thought the next project would be a Pheonix but I got to thinking 1) I already have a hub motor and 2) the Pheonix is really heavy. I have instead *just* ordered the Cyclone. Not too many people have messed with these kits. There was a guy on the old forum that installed it on a cruiser for his dad. He said it had torque that made it feel like a motor bike. I’m hoping for that experience too.

The main reason for choosing the Cyclone was because it would make for a light and fast bike. The motor (with built-in controller and planetary hub) weighs only 7 lbs (which ironically is same weight I hope to eventually loose on my diet)! I plan on using my Milwaukee electric batteries configured 28v @ 12 ah. This makes the complete kit with batteries just under 20 lbs! I’m expecting a top, no pedal speed of 30 mph with a range of 20 miles (at 15 ~ 20 mph).

I’m going to convert my wife’s old REI K2 Camino. It’s not going to be an easy conversion. There isn’t enough room by the bottom bracket and some cables are in the way but I think I’ve come up with a clever solution. I’m having a new 24â€￾ wheel built (the original wheels on the bike are 700c) which will provide the space to mount the motor. The hub is a 7 speed with roller brake. This actually solves the other two problems. Going with a smaller wheel means the v brake brackets are not in the right place so without a roller hub, I wouldn’t have a rear brake. The internal 7 speed hub gives me more flexibility in where I can route cables. This is the theory anyway. The new back wheel will be expensive but it will make it easy to convert a different (either lighter or cooler looking) bike if I want to. I guess I could have ordered a 7 speed cruiser from Target for less money than having a new wheel built but my experience with these big box store cruisers are that they are not built for speed. The level of components is much lower than a bike from the local bike shop.

My main concern is if I’ve missed something with planning and it just doesn’t work out. I’ve heard of complaints with the chain falling off on these kits. I’ve also heard that range is not as good as advertised because the motors are real power hogs. I’m hoping everything comes together in the next 4 weeks or so stay tuned…
 
I think that the main reason they have a reputation as power hogs is that you can keep applying power at all speeds so at 30 mph when your hub is no longer assisting the Cyclone can still be pouring on full power.
I have not had a Cylone but I did have a bottom bracket drive that allowed the same kind of use and it is hard to resist keeping the throttle wide open in top gear. :D
 
When I say power hog, I mean it in the nicest way possible :wink:

The system runs at 24V but the 500 watt motor is said to be able to suck up to 40 amps. They claim that if you keep your speeds low (15 ~ 18 mph) you can do 40 miles on a 24 ah Lithium battery. I'll have 12 ah so I'm hoping for around 20 miles at those same speeds-- which is fine for me.
 
I've actually posted a bunch of pics and a video. see

I'm still trying to get a feel for the bike. Top speed is a little dissapointing-- i'm going to wait until a ride it some more before making broad judgements. I really like the bike though! I think I'll have some interesting conclusions regarding this whole hub vs gearing debate. :wink:

I can say right now that the bike is very light and pretty torquey but, is it necessarily better?... stay tuned! I'm going for another range test tomorrow. I'll try to remember the camera this time and take a bunch of videos.
 
:D Gee, that's great to learn about. I'll go to your thread from here.

Looking at one of the Cyclone pages, is sure is simple to fit (on the right bike frame).

Great pictures there.

IF this were with a internal gear hub, would it break the hub in time?
That's what I was PrEdiCting in the Nuvinci thread, but, aha,
the Cyclone people seem to fit the system to three speed internal hubs.
And so maybe I"m all wet with unfounded worries.
I would think to back off the power when shifting an internal-geared hub.


edit: since reading your documentary thread (so well done, thanks!!), yah, I understand you've got the Nexus 7. So, is it OK to shift these things while full motor power is applied?

Looking forward to your next reports.
Again, thanks.

Great! I look forward to hearing the observations of an objective and rational gearhead...just kidding, Safe.
(shhh... I'm not kidding :D )
 
From my personal experience testing out Johns Cyclone kit the only thing I was upset with was the 30mph claim from cyclone-usa themselves. The kit is a nice kit specially with the nexus hub john's got. But I am one of those people who if a manufacturer tells me "it's going to do 30mph at 24v" then I expect it to at least do 29. From what I understand John spoke to someone personally on the phone.
As for performance It has really good torque and is very light. It's also very quiet for a chain system. It seems a lot more difficult to setup than a hub motor. Comparing the Cyclone to my Phoenix is like comparing a fixed up 4 banger to an American Muscle car. Both have their place.
 
The thing intrigues me, but also I have reservations...no, let's say this:

IF we could have a dual freewheel hub with both freewheels driving an internally geared hub (presuming this hub can survive power-on shifts),

then that's the ideal.

Cyclone's underslung motor is a bit unmechanical.
There's not a lot of chain wrap there either.
It requires their bottom bracket and freewheel chainring.
The Cyclone motor's freewheel cog might be (?) a weak point for durability (?)

(see, I know nothing)

Gee, the present bikes offered by Currie -are- mechanically correct, as these things go. So is a hub motor in its elegant way.

I am all ears to hear more about this new installation.
Break in will improve it, surely.

Maybe it went 30mph on a very aerodynamic bike, with a 97lb, 5'1" import model riding it.

They have down 24 mph for 26ah nimh pack and 30 mph for 24ah of Li-Ion pack. It must be the batteries?
