Full-throttle's 2nd - in progress

Cool vid, what's the power like compared to other motors ? Better than the BPM on similar voltage ? You running the stock current limit on the controller ?
 
The power seem to be similar, but with gears I can control at what speed it peaks a lot better. The suspension also works much, much better (well yeah :roll: ). I don't think a hub motor could climb those steps so easily.

Stock controller, no mods. The only parts I've changed were crank arm bolts, BB lock nut and the chain idler pulley - just because there were some better ones lying around, no need though. Also rotated the motor so the wire exits into the main frame instead of from the bottom, cut away the mount to clear lower linkage and added a small section of inner tube underneath the hose clamp.
 
You got plans to up the power ? It strikes me that with this motor package it needs to be able to offer something over and above a hub. If it's about the same as a lowish powered geared hub then there's no incentive. Weight is similar, handling differences would be minimally noticed by many and those same ones would probably be put off by the extra work of installation. And for street riding it sticks out like dogs balls. Fairly literally :lol: Lets see how she goes on 2kw :p

Awesome video, loved seeing all the grease being used too in reassembly.

250 D8 frames eh? No wonder they are hard to score now!

What do you think of the kit's freewheeling cranks?

only 250? wow. maybe I shouldn't cut mine up...

great vid mate. really nice narrative. cant wait to hear more how this kit performs offroad. any plans to upp the power? :twisted:

2kW sounds good. I'll see if 1kW is enough first though. The last thing I want to end up with is another motorcycle or start shredding components. It's too early to tell now - need to get out on familiar trails and see if I can achieve balance this time. It already feels more capable than a geared hub for offload use and not as dull as a DD. The overlap of peak efficiencies through the use of gears should result in a flat overall efficiency. Can't wait to try it out.

Geared hub is still the best I have experienced for commuting/road simply because I spend most of the time in the peak efficiency zone and there is hardly any maintenance required. Would like to try the Bosch unit though.

Meh. What else would you do with it? :lol:

They pop up for sale now and then. Saw a frame for $200 a few month ago. Even let nechaus and healthyoung know. Don't think they listened :roll:
 
If you do any real climbing at lower speeds, you will GREATLY appreciate the use of the gears. I will NEVER go back to a single speed drive of any kind!! I LOVE my bike now with MY drive and with 1500 watts on tap It will literally climb anything that you can hang onto the bike while climbing!I really want to up the power for the top end though, but I am afraid of hurting the motor... Maybe once I get the new chain ring I want to try, I want to gear it even lower..
 
Just found this thread fella. It's time we all went for a ride! Look out the window!

Who'd be at work today.... Phooey....

Yea I think I was looking at that one, on the rotoburn forum wasnt it? but the guy changed his mind and kept it in the end. lucky, cause I ended up with a complete bike for only a few hundred more.
I'm gonna keep looking for a 2nd though. I like the look of these bikes, and being steel they should be easier to cut up if I ever get to that point.

Yeah, I missed out on that one. Missus would kill me if I bought another frame, have a 2 car garage with no cars in it - but numerous bikes, and a currently stationary vectrix that needs some time spent on it again. Too many projects, not enough time.

Although one of these would go great on the downhill frame :mrgreen:
 
ill go riding with you sometime when i finish up my bike, should start a thread....
Oh and i totally forgot about ur PM, think the boss said $50
 
Full-throttle, I didn't like the looks of that power lead coming out the very bottom of the assy. either. I remember the motor casing having some dill/taps (bike is in garage waiting for brakes, cassette, etc.) that would have to be redone in order to rotate the motor/wire-lead exit to a more suitable location. Did you have to drill/tap any new holes?

I'm looking at 20 aHr LiFiPO4 packs (heavy!) because I intent to use my Cannondale F5 like a KLR Kaw... ADVENTURE (easy 20 mile range) BIKE. However, I noticed you are using a state-of-the-art LiPo pack. Could you PLEASE tell me your impressions and provide a link (got one?) to some real world pack builds and usage. Any info would be great.

Enjoyed the video, excellent camera work, music selection, editing. Good job, thanks.
 
Great video, even better build.

The rippin synth solo into the first test drive footage was our favorite part. NICE!
 
Thanks guys

Yeah, def start a thread! Is it the Marin? Don't stress about the controller - I put his back and it started working again. Prob just a loose contact..

Undo all the bolts then rotate the core anywhere you like. The pack is made from HK 25C LiPo, I'll post some pics later. Search for jonescg and his LiPo packs for sale if you're after something similar.


Just came back from a short ride. I def need to far a chainguide :oops: Highest gear is skipping, but on the flat in 2nd it gets to 43kph, no pedaling. Measured with a gps and averaged there and back. Current peaks at 21A. No load current is 3.7A, which is less than expected. It's a noisy bugger :twisted:

The bike handles like a dream, def better than with MAC. In fact, it climbed a short rocky 20% pitch without struggle. MAC @ 1.5kW on the same pitch bogged down while the Bomber was wheeling the whole way @ 4.3kW.

There might be another short video tomorrow night :wink:
 
Thanks for the feedback, Full-throttle. Goon intel!

Chain derailed (a few times) on my test run using an old Wally World bike, broke some teeth on the freewheel cluster as well. Glad you mentioned a chain guide. Gotta put that on the list of needed parts.

Found an old 14-26? cassette (7spd) for the F5. May test with that, but plan on a 11-34t for later, true versatility. Any recommendations for a "good value" derailleur for that king of range? Doesn't have to be bullet proof as I intent to shift off throttle as needed. Maybe a chain guide would allow me to go for an 8spd? Hmmm
 
Ordered a 48V, 20aHr pack and a 13-28T cassette yesterday. This is my second and last pack to order, next one will be a DIY job. Looking forward to resuming the test.
 
Any way you could make this available for mobile as well??
 
Can't see it on my mobile either, will have to wait until i get home, was looking foraward to this, this is standard gng setup at 48v right FT?


D
 
Yep, unmodified GNG on 14s (58V hot)

re: no mobile devices - if there's a way of turning it on I'd like to hear it
Edit -> Advanced Settings gives me this:

No, this video should not be available on mobile phones and TV.

meh
 
Could just be the format of the file, i was trying on iphone and we all know apple doesn't like to play nice with the other kids, prob fine on a windows cell :roll:
Very cool vid FT, the gng looks like it does a very decent job, must be great to have no mass in the wheel too - a slightly cheeky ask but do you have the same vid without the audio overlay? i really want to try to get a jist of the noise, something that always put me off a cyclone.
I wonder what he standard drive can take power wise, it's not like we dont have the skilled members to mod one to take a little more bearing in mind the standard drive train will only take so much anyway, when i ran the 3210 mid drive i was very happy with having all that plush travel working as it should however the noise was obscene lol, hoping this is quieter, certainly would like to have a tinker with one at some point, oh and yes the bike looks awesome ;)

The sound track is what usually creates syndication issues. I've found most of my vids wont play on mobiles if they have a copyrighted sound track. I think it's to do with youtube mobile apps and adds - they often don't display properly so they just block those vids all together.
 
It's def the soundtrack - the videos without have
Syndication
Everywhere

No worries, I'll put one without the music on tonight, easy.

The drive is noisy but not too bad. Not as loud as RC. Power wise it actually feels fine. I'd give it another 50% at most, any more and it will move into a motorbike territory. Which will need stronger parts, more Wh and wouldn't suit my style of riding. I know it's not everyone's cup of tea but it's nearly perfect for me. It's nice to be able to bunnyhop again :)

The first thing to fix is to make a chaingude :twisted:
