[QUOTE=curyam;6858841]Here's my ride a Geco C-1. Made by Geco Bike Company. Lithium Iron Phosphate battery. 350 watt front hub motor. Mag alloy frame


How do you like this bike? Can you please give a review of this bike? I'm very interesting in buying one myself. I live in Seattle, and it looks like the distrubutor is located here.

My Cyclone EXP
 
My Cyclone EXP

Hi members,
i got myself a 650 watt cyclone kit about 1 year ago and before even riding a single minute have done some serious reengineering to solve the following:

1. In tough terrain the motor overheated quite often. Ive machined a new motor housing out of a solid aluminium block and integrated cooling fins.
2. The freewheels are not sealed so dirt can easily get inside. By making a protective housing for the freewheel that now features shim rings no water or dust can now damage the inside.
3. The original motor mount was replaced by a new one made out of aircraft aluminium. The clamps that hold it to the frame are also made out of one solid piece.
4. Yes, the planetary gear box is now 47mm shorter thus enabeling me to fit the motor inside the bikes frame at the center of gravity. This was another month of work using mill and lathe.
5.The battery box at the bikes back is also made out of metal and holds things in place even when jumping around off road.
6. All the wires that go in and out of the motor / controller were replaced by highly flexible silicon cables and this time water stays out.
7. This is off topic, but the headlight features a 5 watt LED with a custom built dimmer and was also made out of a solid block of aluminium.

... and how does it work. I love it. I know im bragging a bit, but after almost 900 hours of work in my machine shop this setup really gets things going. To this day ive ridden more then 3700 Km under hardest off road conditions here in Spain at high temperatures. Nothing failed on me to this day. But i must say the way i got this kit it would have probably died on me after a short ridden distance. I also wrote Paco ( The guy at Cyclone ), sent him pictures and never got an answer. But hey, they didnt design this thing anyway!!! Check out headline electronics under:

Hey Martin,

I really like the set-up. Nothing like having a rear suspension at high speed!

And the planetary gear takes care of that 10 to 1 problem. Great, efficient, light.

I also had that chainring on my e-bike at first but because I had to do the demultiplication through it, I actually had to had another chain and a freewheel atop the freewheel in order to pedal so I discarded it.

The use of chains and locking bearing does have it's drawback however. The Klonk-klonk noise when applying pedal power or accelerating with the motor requires a little smoothness on the throttle.

Seems like you're enjoying, have fun!

The C-1 is a very rewarding ride. Fairly lightweight for an E bike. Under 50 lbs. Getting pretty good battery life. I don't have a odometer yet but I've been going pretty long times between charges. Nice stable ride. Battery in back and motor up front really helps balance with this machine. Good at speeds and crusing however it still not a road bike. The bike still needs some fine tuning, front shock a bit soft, the throttle needs adjustment, but other than that it works quite well. The Shimano 7 speed nexus hub has a really good spread of gearing. Internal rear brake and front shimano rim brake work very well.

More later.

Here is a pic of my homemade eSUB (electric Sport Utility Bicycle). It has a 48V 500W Grubee SkyHawk hub motor.
I still have detailing to do - tidy up the wiring and give it a paint job. I am also going to extend the bike rack towards the rear wheel. As you can see from the pic I have a full rear wheel's length of cargo space available. The existing bags are completely occupied with racks and batteries - two SLA's on each side.

PVC Quadracycle with Cyclone drive
 
2 Attachment(s)
Friends
For the past month we've been having a blast cruising around town in our PVC quadracycle. Wanting the ability to haul 2 people up at least gentle hills, I liked the idea of the gears in the Cyclone system. And since I have a couple of extra wheels, it was easy to set it up without the need for the freewheeling chainwheel. I was lucky and the motor fit in the frame easily. It's worked out quite well, just need to remember to gear down before approaching a stop.

BD36 help
 
Howdy,
I'm putting a BD36 on my Townie and I see you have a similar setup. Is that a thumb throttle next to a grip shifter? How do you make that work?
Thanks,

or maybe you could get a nuvinci hub and you won't have to gear down before you stop.
cool machine :thumb:, does the pvc flex much?

Sianelle 07-07-08 05:56 AM

I'm curious too about the durability of the PVC frame.

The PVC frame works surprisingly well. It is reinforced with 1 3/8" aluminum pipe in the bottom frame members (the plans call for steel fence rail pipe, but I have a local salvage yard that had aluminum for a bargain price). It flexes enough to soften the bumps out fine - no shocks needed! When going over rough, uneven pavement you can occasionally see one wheel in the air for a moment. Seems to be strong enough, but it does make creaking noises sometimes. How long will it last? We'll find out.... We have a little over 200 miles on it and are extremely happy. We're traveling for about a month at the moment, so it's parked right now. We've had a little problem with the aluminum steering arms bending so that the front wheels get out of alignment easily, causing drag and wear on the tires. Not sure why this is happening - I'll take a good look at the geometry when we get back, may need to just swap out the aluminum arms for stiffer steel ones. Also, when going up hills (not steep at all, but long continuous) with 2 people if you go too fast and don't gear down and throttle back a bit the motor will get hot and cut out. After a couple of minutes it'll run fine again. It feels like it has more than enough power to climb hills, but I think that running 36V in a 24V motor is what's causing it to get too hot. May try to add cooling fins like a previous poster.

Still need to do a little work like adding cup holders, a radio, I tested the water mister system but haven't installed it yet.

That Nuvinci hub looks cool - never seen it before. maybe for the next build...

It was the front axle/kingpin/steering arm assembly that worried me most about the American Speedster design. The PVC chassis frame is fine and I'm sure would be strong enough for the purpose as well as having a reasonable service life. BUT the design of the steering and kingpins is just not good enough in my opinion. To my mind the axle needs to be redesigned to use steel tubing and scrap bicycle steering head assemblies at the very least in order to be safe to use in a serious fashion.

My entry bike into electric. Not sure how good a bike this is, but I got 2 bikes (1 working), and 3 battery packs for just over $200. Any insight into this model? - eb electrobike jazz? The battery packs are 36v sla, and the motor is 350watt brushless.

I also just got one of these from Ebay (delivered as seller is in Melbourne as well) and although I have only ridden it a few times, so far its pretty cool.

WoW!

Where does that come from ? Any URL? (I'm afraid to ask how much you paid for it...). From the picture, it has a rear hub motor and the chain ring is demultiplied right at the BB.

Very nice

Here's my ultimate commuting machine.

Attachment 76619

Bionx PL500HS (500W with 10Ah 36V Lithium Mn battery)
Soma Double Cross frame
Nashbar Carbon Fork (disc brake ready)
700x23 front tire (120 psi)
700x28 rear tire (85 psi)
7sp 11-28t rear freewheel
39/53t front chainrings
clipless / platform pedals (for mtn shoes or regular shoes)
Fenders for the rain around here
Lights for night riding (not pictured)
Topeak MTX rear rack with quick mount (got pannier and basket to go with it)
Klickfix handlebar mount for detours accessories
Bell to help me be polite when passing

The whole bike weighs 48lbs. At level 3 assist: 45 miles range and top flat speed (that I can do at 90% effort) of 31mph.

Very quiet since it's a hub motor. And pedal assist (instead of separate assist switch) makes it still feel like a bicycle.

Only essential thing I'm missing is a water bottle holder. Need to find a way to get one in that space in the frame.

Zeuser, That Yamaha bicycle is really something. I searched google for info on it but none found. I'm interested in the specs for it, if you have a link.

Here's my new urban assault vehicle; an eZee Quando II with a 250w, hub geared motor and 36v NiMh battery. I added the Miracycle mirror and Vincita panniers from an ebay auction.
The smaller wheels and wheelbase provide maneuverability from street to sidewalk in my urban environment and the folding capability is a plus for travel holidays.
