GT i-drive 2.0 Build

the leak is on the inside of the tube, 10" from the valve stem. rode fine for a day at 40psi but i pumped it up to 60psi this morning.

last time it was 6" from the valve stem. time before that it was glass that broke the wearing tire.

i've checked and rechecked for protruding burr, but probably better put on another liner to be sure.

...and lug around the big crescent wrench and patch kit till i get some miles under it again. just happy it worked for client presentation on monday!
 
so correct me if im wrong, but the andersons are being a weak spot in the current flow, not letting the power through? and you want to keep plugs so you can charge as separate packs still?

you probably know these, but in rc we frequently use a plug called the "deans ultra". it is a small, T style plug that can handle a rediculous amount of power ie, 100A easily. if soldered correctly, they are generally regarded as able to handle whatever a 10 gauge wire can, official specs say a 0.05v drop over a plug, so they may be worth looking into.they will basically handle anything you throw at them...

if the space is tight they are the perfect option, otherwise they can be a little small for people with big hands to easily pull apart, (never had a problem with mine though) traxxas also makes a plug similar to the deans, but its bigger, so easier to grip, also a different style. never used the traxxas brand, but reports put it on par with the deans. every model store will carry the deans, probably the traxxas as well. for less than a couple of bucks a pop, it could be worth a try...
 
Hi G

Yes maybe a good idea to drop the power a little your power loss through the contacts will thank you 8) they are rated up to 600V but the spec sheet rates them up to 30A @ 120V, again ohms law comes in to play again if you increase the voltage your losses go up in square proportion.

Soldering helps as it doesn't deform the cable entry shell, reducing the connections is a good idea though, I have 4 packs total of 16 connectors, they get only mildy warm, I may in time also solder them all up, I think I will certainly solder 2 packs up (including the balance wires), however I do like to be able to configure different voltages for my other rides, I haven't had any real problems so maybe will just leave it, you also get to check at cell level all the time which I like.

I find on my rides that I wear the rear drive tyre around the bead even quality tyres! its so annoying, I dont think they are spinning in the rims either, you know its on the way as the high pressure in the tubes makes the tyre bulge out where its going weak then the tube will pop out and thats when you get the pinch flat :evil: its annoying to have to ditch a tyre that has minimal tread wear but has gone on the bead.

If anyone can recommend a good tyre with a strong beading I would love to know, I was using specialized armadillos as well and they still went :roll: I have learned the hard way to definitely not fit cheap tyres, they never are true on the rim and wear so fast.

I had a number of recurring flats once, it turned out to be the rim tape, all my flats were on the inside of the tube? after three flats I found the problem was the cheap plastic rim tape had gone hard at the edges making a very thin and sharp hard plastic edge, this was cutting in to the tube, esp as the tube was at high pressure, I simply changed it for a softer rim tape and the problem went away, it can also of course be from a broken spoke, long spoke or burrs on the rim holes cutting through.

I got me some new tyres and tubes coming nice and cheap with free shipping 2.4 as well so nice and chunky going for just 10 pounds, continental mountain kings (with the bad weather on the way time to drop the slicks) hope these will fare much better?

That Mountain King tire looks like it's going to wear out in no time. There's barely any tread - just a few knobs...lol.

Check out Hutchinson Pythons, I had those on a mtn bike (actual mtn biking) and they rolled fast on the street, yet still have good tread for most dirt conditions.
 
ha, looks like you need a 55 tooth sprocket,i find my 58t is perfect at 30-35 mph. 55ers are easier to find.cool vid.
 
Do find that the rain jacket/pants slow you down noticeably? Or increase your watt hour usage?

no. if i were pedaling hard, i might notice the slightest difference, but heck, i'm standing up half the time, partly to see over traffic, but mainly to be able stop or move quickly. the benefit is staying dry! everyone is amazed i ride in the rain. with those, i don't mind... though they are getting beaten up now.

beast, i would love the bigger chainring, might make pedaling more worthwhile..

here's a better rear view, virtually uncut this time:

more intense inspection/wiping of the existing liner, rubbing with finger, licking... (just kidding).

still holding my breath actually, till i get in there and put a wide strip of cut up tube as a home-made liner...
 
Hi G

Yes done that before and it works well!! I cut an old inner tube and stapled the ends with an office stapler, I joined the ends of the tube through a piece of card. I had to do this as my rim was so wide! it has been working like a charm since and is made out of what was essentially trash! cool 8) will watch the latest video from the GINDC show! after work tonight, loved the last one with the kids in the trailer!! way cool. 8) :)

Office staples inside the tire :shock:

I use old tubes to make rim strips. Clean them well to remove talc and other stuff and use crazy glue (ca) to join overlapped ends.
 
yes staple ends were taped over to avoid any problems :p

Loved the last vid G just sat here nodding off after a hard week at work about half way through a nice bottle of red :mrgreen: and figured your video would be a good tonic to keep me awake, just amazes me what a great commuting tool you have there, I also liked the little race you seemed to be having with that white truck, very cool 8) everyone of your vids i have now downloaded look great played back on the big screen!!
 
yes knoxie,those must be great on a bigger screen than a 10 yr old laptop :oops: .
big chain ring is easy just buy one 55toother hold it up against your outer sprocket mark any available spots to drill and get some good nuts and bolts,i did mine for 8 bucks 5.00 sprocket,hardened locknuts bolts 3.00.can go either inside or out depending on your crank setup and chain line.

thanks, knoxie. the white truck was actually a USPS truck. i was surprised how fast he was going. i did see him leaning out a bit, steering from the right side, lol.

but what i love about this run, up Connecticut Ave is that i can go almost top speed and catch the lights perfectly, leaving all the cars at a standstill. there's just enough room to play on the right side where cars are still parked from time to time, and enough that other cars don't try to drive that lane. i think i've got a decent one of the route from the front.

here it is, but i guess i'm in the flow of traffic, not punching through each light (will have to work on that):

beast, you do make it sound easy. i'll have another look.
 
Yea :)

Now I am wondering what kind of snow bike I will be running :?:

I have not been able to find any studded motorcycle tires (17 or 19 or 16") that can be used on the road. So I gotta go back to a 26 or 24 or 20 bicycle rim :roll:
 
Looks like you could fit a plow to the front of that one!

Should I go back to a hardtail 700c for light weight? Or a front motor 700c?
 
Hi G

Yes looked at the video again I reckon he was trying to catch you up to get a closer look, I am sure a lot of folks have seen you and have commented to other people "like theres this guy and he does like 40+ in and out of traffic and he aint peddling?? hows he doin it? ha ha maybe its that guy David Blaine?"

Looks like magic anyways!!

Keep the videos coming!!! love the rear facing shot, you need to kid the wife in to letting you have a 960 so you can shoot front and rear at the same time and splice them together!! ha ha.

Have a good weekend!
