I've had troubling experience with shipping out of China with these stuff. I'm going to Hong Kong in two months to pick up one of this kit from GNG themselves. Anyone thinks TSA will not let this on a jumbojet checked baggage to the US? No batteries of course, just the motor kit. TSA says power too...

I would bet on that frame, you could get a GNG above the down tube instead of under it.

by flyinmonkie » Sat Aug 24, 2013 7:21 am If done right, chain is not noisy. You need to stay away from small sprockets and get it aligned well. Why would you say that when Christerjung has just done a high voltage GNG chain drive and it is noisy as an RC motor, maybe even more then a cyclone as RC...

If done right, chain is not noisy. You need to stay away from small sprockets and get it aligned well. The cyclone will always have a high pitch whine due to the straight cut gears in the planetary reduction. From reading the posts, the GNG is far easier to install than the cyclone. Especially the o...

Noise is subjective. I ran mine at 50v off the charger. Yes there is gear noise from the gear box, but it was not as loud as my brushed currie motor. I have not heard a hub in person, but in all the videos I have watched, they are far from silent. The biggest difference is the pitch. The cyclone has...

The bike has sold. I have told the new owner about the sphere and will give him a link to this thread so he has more history. I may be quite for 3 or 4 months now, but I'll be starting a new build or 2 once I get settled in the US. Looking forward to building a couple of new bikes. they should be go...

Glad you're having fun in WI Greg. I'll be in that neck of the woods permanently just in time for winter. I'll have a new bike or 2 made up by next summer though.

Nice work Kim,

Glad to hear it is up and running and living up to expectations. Looking forward to seeing some video soon.

You definitely need to adjust the gearing. You either need to build a gear reduction from the motor to the crank. Or change the crank sprockets. Or change the final drive sprockets. It will all depend on if you want to pedal along with the motor, or want the motor to even drive through the crank. Th...

Have you adjusted the gearing to compensate for not having the gear reduction in the motor? That could drastically change the feel of the bike and be very destructive to your controller if you haven't.

Email cyclone tw and ask for the actual shipping cost. Their website shipping calculator puts everything way over priced. Paco should give you a reasonable price then.

Well... it is time to sell this bike, as I am moving back to the US and it will be too much of a pain to bring it with me. It is all finished except painting the box, if one wanted too. It is a great solid bike and will be sold with an extra set of slick tires and the hyperion 1420i charger and powe...

I want to convert my 9 speed derailleur setup to a 1 speed with a solid chain tensioner, since I am getting a lot of chain skipping/dropping when accelerating hard/jumping and I'll be upgrading to 100v soon which will make the problem even worse. I was thinking of using the DMR STS single speed kit...

I don't see a dérailleur on the hub motor or a way to take up the chain slack if you were to change gears. It also looks like what I am guessing is a chain guide is in the way of the pedals, making them non functioning. Of course this is just from looking at the pic you posted spinning.

If you are ordering from paco at cyclone.tw, then you need to email him for a shipping quote. The website calculated shipping is wrong. Most people have had a good experience dealing with him.

Finally got the last 4 batteries put in. Was super easy to just slot them in the box and plug them in the bus bars. I now have a total of 23.2 ah. I haven't had a chance to ride yet as I let all the cells even out and then balanced them. That is it except paint, but I don't think I'll paint it. I ca...

The first bike I made went through the crank. I hated it. It was a lot harder to gear the motor to the crank speed. I also did not like the crank sprocket spinning while I wasn't pedaling. With my current set up I can adjust the motor gearing and the pedal gearing independently and therefore It is m...

rp3 Like christer said check your alignment, also lube the chain. I have a #25 primary drive chain on my bike (not GNG) and it gets louder when it needs to be lubed. For tension, there should be a bit of flex in the chain when you push on it with your finger. It is not like a belt that you want real...

Thanks Greg, it's good to see some good in the world. Also good to know I'm not the only one that stops to pull people out of the ditch. Of course I just enjoy pulling people out of the ditch for fun. Helping someone is just an added bonus for me. he he

The headline motor (cyclone and aft) gearboxes are better than they used to be. From what I have seen here, most people that have bought one in the last couple of years have had little to no problem with them. Of course if you often crack the throttle wide open and shock load the system all the time...

Just to add my take

Clay

hillyterrain - The bottom bracket can only go one way, as one side is right hand thread and the other is left hand thread. Several other people have found that the sticker on the GNG supplied bottom bracket is on backwards. Cheap bottom brackets. The plates that hold the motor go between the flange ...

AW, my thoughts are with you like so many others. Luke has said it so well, and I can not add anything to what he has said. Be strong and know you have support from everyone. Take it one day at a time and keep moving forward.

Clay

We don't really have any idea of what sort of temps the frame has seen from the fireball. Obviously parts did not get too hot as the paint was still intact. But some parts may have gotten fairly hot. So the frame strength is a bit of a question mark as it is. If you weld a box in, it can be over bui...

Some people have had luck with the isis set up from cyclone. You can order just the bb or the whole crank set. You loose the support bearing that the GNG has though.
