Hi Guys, this motor looks great. I'm look for a replacement for my cyclone 3000. I'm running it at 72v and am having overheating problems. This motor looks much better built. I wondered if someone could confirm the weight. The spec sheets suggest around 7kg which seems a bit much? Do you think...

I've had my cyclone for a a while now and wanted to share my experiences with throttles and controllers. I run a 20s4p 72v nominal battery pack. - stock - loads of power but the power delivery is very jerky, the controller is large and the throttle is cheap and poorly made. - I upgraded to a...

You could do kits, some youtube videos and have a few threads on forums to address support. That might help avoid onerous support. Still very keen :-)

This looks awesome. I'm super interested. A polished product would be great but I'd be happy to pay for kit that I had to solder up if that reduced time to market. Got a bit of time on my hands at the moment

Hi Motorman, Thanks for your kind words, good to find someone thinking along the same lines. Actually I built this for offroad and it's absolutely mega. I ride it like a stole it and it seems to be holding up quite nicely I did have a 30 odd tooth sprocket connecting the crank to rear wheel and...

Just posted a build thread entitled Specialized Enduro 2014 Cyclone 3000 build in E-Bike Build Threads / Photos & Video. I included a brief description, pictures and a link to a video. Thanks very much to everyone for all your contributions - couldn't have done it without you.

Hi All, Just wanted to contribute something with a few words and pictures of my cyclone 3000w/ specialized enduro 2014 build. Thanks to everyone for their forum contributions and ideas - I'm definitely standing on the shoulders of giants. I have a ktm 2 stroke enduro motorcycle which I love to...

Really sorry but I'm flat out with work so don't have time right now. I took loads of pictures and will do a proper build thread soon. The motor mounts attach to the crank same as the stock mount but also attach to the rear suspension mounts. I used longer bolts and spacers so the suspension...

My cyclone build, thanks everyone for all your help and ideas.

Lived in London for more than ten years. It is extremely congested. If you are involved in an accident with a non legal high power ebike they will crucify you. I wouldn't even consider it. I'd go 100% legal for the commute and high power for the weekend. Also the public transport is pretty good.

I've wrapped the batteries in loads of capton tape and heatshrinked. I'm going spray the cases black inside and out as well. I really hope it 'll work well - I've spent so much time on it. I'll post a full build thread when I've got it going. Thank you to you and everyone else for all your help.

Updated my profile, sorry about that. The surface area of where my clamps touch the frame is 12mm (width). I was thinking of making the sleeves at least 4 times wider, maybe the maximum allowed by the space available. I know your're saying re the lack of reported failures, I've spent a bit of...

I'm hoping the batteries will be ok as they're enclosed in a 3mm thick aluminium boxes. I am a keen off road enduro motorcyclist and crashing is one of the things I do best! Hence they obsession with durability. Here's a pic of my battery boxes https://imgur.com/a/00UlI

The thing is the batteries have a combined weight of maybe 5kg. If I clout a rock a speed the forces will be significant given the downtube is only around 1mm thick and a don't want to ruin my nice mtb - hence the cogitation:-) I like the idea, unfortunately its pretty difficult to cut hold of...

I think that the frame would perhaps dent and then maybe break at a later date once weakened. As far a I'm aware mtb frames gain a lot of their strength from their shape. I'm waiting to see what the steel looks like when it arrives, I thought I might use multiple layers if it looks a bit weak...
