    Guru advice for super large rider

    So apparently my notifications aren't working. I hadn't realized people had been posting on the thread. Notifications worked for a while. I also figured out my weight was going to require something like 4000ish$ to do just the electrics. I wasn't really thrilled with that. Now we're talking 6K...

    Nissan Leaf Cells Test Data

    Gotcha. I'll go back to lurking-ish. Or sponging anyway :). Just trying to be helpful in the one area I can contribute on.

    ≤2000w 96V charger ~$5

    Man I hope this is tongue in cheek :) ... kinda like the "wow, I found a great way to charge my iPhone in the microwave in only 1 min!" and then you see the people who tried it ... Speaking first hand as someone who put a handheld electronic device in a a microwave for fun (knowing exactly...

    Nissan Leaf Cells Test Data

    Hi all. I had it pointed out to me in PM that I speak authoritatively on Li batteries. So I'm a noob here in all ways but one .... I know way more than I ever wanted to know about lithium batteries due to part of my work responsibilities :). But, hey, I can contribute and not just be a sponge...

    Solidworks models, mid-monster and others?

    adriftatsea: Legal copy. Not a personal copy, is used on a work computer with work permissions for after hour use. I did look a little into the toolbox and I'm not sure our corporate install has the full toolbox, but there was some stuff. Thanks for the other links. I'll check them out. Miles...

    Solidworks models, mid-monster and others?

    Hi all, I'm working on designing my custom trike in Solidworks first. I'm thinking of using John in CR's Mid-Monster. Has anyone modeled it before? And just for giggles, do any of you have any other collection of models that you'd be willing to share? ... I found "GrabCAD" and found a couple...

    Guru advice for super large rider

    Lol. I get the hint :). I'll probably start it in a couple weeks - basically as I'm finishing up the CAD changes from this round of feedback (e.g. starting over :). I expect my build to literally take all winter. I'm just doing it on weekends or maybe an occasional evening - and have two kids...

    Guru advice for super large rider

    Hi Teklektik. As usual you're full of great ideas / info. Thanks for both postings. I had stepped away a bit this weekend and was planning on thanking you for the data plots today :). I do have near slicks on the motorcycle tires. I figure the midmonster, two controllers, CA, and battery pack...

    Guru advice for super large rider

    FWIW, these are the wheels I already bought and still plan to use .... till I'm convinced otherwise. They're stupid strong and have real bearings. Everyone is saying "Go small because they're stronger". Well, there's no chance in hell these aren't strong enough. And I think I can change the...

    Guru advice for super large rider

    teklektik: I think we got disconnected somewhere. I did chage to what you're talking about - mostly. Delta, dual / redundant drive / etc. No mid-drive. The most likely right now is mid-monster geared to direct drive the hub (or jackshaft as you're talking about - but in either case, will be...

    Guru advice for super large rider

    John in CR: I was looking around for your mid-monster and trying to understand it a bit better and I found your comments in a thread that to my simple mind look sort of contradictory. I'd appreciate your help on this. I'm sure it's not inconsistent, I just don't understand the different thought...

    Guru advice for super large rider

    Hi TC Yeah, I've worked through every combination known to man I think on how to lose weight. I haven't gone as hard-core as LFP, but I have done serious calorie reduction and about everything known to man. And .... it all fails for me. This series is the ONLY thing I've ever read that is like...

    Guru advice for super large rider

    FWIW, I haven't told anyone my real name - not out of secrecy - just didn't. I'm also a John and live in in a KC suburb. IdleMind:Good advice. The axle mount to spindle was a concern of mine. That's one of the parts I was going to have professionally welded. Nothing like having a wheel come...

    Guru advice for super large rider

    amberwolf: Thanks for the thoughts on the smaller tires. The wheels I have now are Honda "Comstar" wheels - basically solid center for all intents and purposes. Not spoked.I'll research gearing and if it's looking bad I'll switch over to a smaller wheel. Also, good datum on the 20" + HSR3528...

    Guru advice for super large rider

    MadRhino: Yeah, mid-drive is off the table. I figure I’ll baby the first batch of the highest strength bike components I can find and see what happens. I looked a bit yesterday into go-kart transmissions and I didn't see anything I really cared for. I'm either going hub (one of John's Monsters)...

    Guru advice for super large rider

    Jonathan in Hiram: You are completely correct. The walk of shame would be a very difficult thing for me. I have a small loop in my neighborhood I plan to do a LOT of my test drives on until I'm sure I can get a bit further away w/o exploding things. I agree on the dual drive systems for a...

    Guru advice for super large rider

    Again thanks to all for your inputs. It’s certainly steering me down a different path than I had anticipated and I’m very glad for your thoughts and input. docnjoj – Oh boy. I think modifying a round tube suspension framed bike … yeah, maybe that’s mark 3 . wineboyrider- thanks! I am now wary...

    Guru advice for super large rider

    And, if anyone has any pointers to threads about or references to any higher strength gearing options I'd appreciate them. Anything that's not hundreds of extra pounds to the bike but can handle the strength of my pedalling w/o disintegration (e.g. a 219 chain version of a derailleur setup, or a...

    Guru advice for super large rider

    John in CR: Thanks for your thoughts. The tadpole I’m working on in Solidworks should have the seat high enough to get in and out of and I’m pretty confident the step-over wouldn’t be hard for me. Strangely as it sounds, my body frame is built for carrying massive weight. At 400 lbs I was in...

    Guru advice for super large rider

    Thanks MadRhino. Why do you say big guys need small tires? SpinningMagnets - Hello fellow Kansan! I noticed you were semi-local and a super guru. I've read all sorts of things that you posted. And thanks for the moped tire link. If there are any other good threads or advice I'd appreciate them.

    Guru advice for super large rider

    Hi Drunkskunk. I appreciate your thoughts. I also think it's fun, which is another reason I've been working so hard on this - way better than being bored looking at silly pictures and watching netflix every night). Never heard of midmonster. I'll look into that. In essence my plan is what I...

    Guru advice for super large rider

    I should also add I spent 1.5 months reading every single night (and talking to vendors) before deciding yes, I wanted to fabricate. And I know good and well it's easily the biggest project of my life - even bigger than the 12x20 workshop I built with full electric, etc :). The amount of...

    Guru advice for super large rider

    I'm fairly committed at this point to making my own. Not only do I think it's fun, I know I can fix anything that breaks and make it out of much stronger materials in the first place. Budget? .... what budget :). I'm looking at it like if I don't do this I might as well go ahead and give up...

    Guru advice for super large rider

    Thanks to those so far. 6' 1". And yes, holy smokes :/. Been a life-long struggle. Part medical, part behavioral. Combined = toast. I did look at worksman cycles. They couldn't guarantee or even give me warm fuzzies about the tires holding up. Even with kevlar and all the bells and whistles. I...

    Guru advice for super large rider

    Hi all, I've been researching for months and I'd appreciate any review of my current leanings to make sure i'm on the right path for my specific weird situation / disability / whatever you want to call it. I'm near 700 lbs. Yeah, I know. I carry it very well for 700 lbs, but it's pretty hard...
