    Some Ideas on building a 5000w E-bike

    Another question I have: How effective is the regen brake on a back hub motor? Depending on what frame I use, I may not be able to put a rear disc brake on it. Is the regen brake along with a 203mm hydraulic front going to be sufficient (at stopping from 50mph)? I'd rather hold out on a full...

    Does anyone els have issues with aligning rear disc brakes?

    Yes, this is common. And, it usually is the rear caliper that wants to walk when torquing the bolts. The best practice depends on whether you have pad adjustment knobs on the caliper or gimble washers (all avid brakes have this, not so much the others). If you don't have gimble washers, try to...

    What is your preferred cruising speed on a bike trail?

    I don't have a neat ebike yet, but I'll cruise around 19~24mph for the whole ride. I'm not a rude commenting leg shaver, but I'll chase down and pass people who are also fast. Practically no one has ebikes around here.

    The Greatest Story Ever Told

    I am extremely confused now. Gonna leave this one alone. EDIT : No, actually, tell me what you think of this animation, electricridefl ? It's a rotating 3D cross section of a seven dimensional hypertorus. You can create this animation with the equation (sqrt((sqrt((sqrt(x^2 + (z*cos(t))^2) - 8...

    You think the posts on the subreddit simulator are real people?

    Im going to say something very controvertial. SPEED.

    Lol, Chalo, have you ridden a $12,000 race bike before? The sub 15lb full carbon everything, on tubulars? They're amazingly efficient. Exceptionally fast. Now, couple that to a top level cycling athlete (think Pro 1,2 category in the TDF) who have a 450 watt lactic threshold (effort level...

    The Greatest Story Ever Told

    Wow, I'm surprised you guys have allowed this bot to live for so long! They can be more sophisticated when implemented with markov chains. It basically uses the entire forum, or sections of it, as a pool of sentence fragment choices, and puts them together (more or less). Usually, it posts a...

    Some Ideas on building a 5000w E-bike

    I'm also trying to fit 5kWh on the bike. I guess that can be accomplished with two separate 84V 30Ah batteries. At least somewhere in that range. If there's anything I'd rather splurge on, it would be some ridiculous range. I think it would be a good idea to have such a vehicle, for many reasons.

    Im going to say something very controvertial. SPEED.

    Just to put some numbers to that: A top athlete on a road bike can do 45~50mph in a flat-out sprint, and maintain 27~30 indefinitely w/o drafting. You're average fit roadie can maintain 20 and sprint to 35 or so, on the flats, no wind. --------------------------------------- But, I totally...

    Some Ideas on building a 5000w E-bike

    After doing a lot of reading around, and going through all of the "I'm a noob and want to go 50" threads, I have decided that 70mph is too much for a first ebike. I'll keep it at 50, the original plan. Realistically, I'll be going 20~30 for 80% of the time, when I ride this thing. So far, I came...

    Some Ideas on building a 5000w E-bike

    I don't remember which recumbent was the twitchy one. Might have been a BikeE or something. They weren't all like that. Some handled really well, just like a road bike. I could see myself putting a motor on it, too. Well, you guys would be proud of me. Today I agreed to take on a project to put...

    Some Ideas on building a 5000w E-bike

    Yes, that's exactly it. I love recumbents (also worked at Catrike), but I don't have a lot of miles on them. I certainly don't want to go 50mph on one :) . I've ridden many, either a customer's tune up or a new assembly. Some were very smooth riding. But that's still 50 miles compared to 30,000...

    Some Ideas on building a 5000w E-bike

    My god, popping wheelies on a recumbent .... that's a lot of torque! Well, don't get me wrong. Doubling the range for whatever build is an attractive feature. It's the handling characteristics of a 'bent that I don't want for high speed. I just feel like they're too twitchy. But, that seat would...

    Some Ideas on building a 5000w E-bike

    Hey, thanks for the responses, everyone. I'm sticking with these specs for the build. It's just the way I want it. Part of the fun will be testing its range capabilities regarding speed, and other factors. I'll get another, duplicate super-battery when the funds allow. I'm very impressed with...

    Some Ideas on building a 5000w E-bike

    Some specifics of my first-time e-bike project, • 26" wheel with a 5kw hub motor. • 50 mph max on flat ground, to start off with. The power level seems to be capable of 70, but that will be for another time. Overbuilt = durable. • I'd like to be able to cruise at 30mph for 60 miles, just to...
