    Hub motor recommendations for a cargo bike in a hilly town

    I've been running 52V 20ah BBSHD on a Madsen longtail bucket bike with 2+ kids for 6 years, and I can say that the BBSHD is both the Least Powerful AND the Most Powerful motor that is good for carrying 2 kids in hilly area. Any less power and the 0-3 mph dead zone is in danger of tipping over...

    "60V" New Retail Trend - 16S or 17S?

    After a few years away (happily using my BBSHD Cargo Bucket bike with the kids), I return to EBike hobby with the hope that my DIY Zip-tie and Duct Tape days are behind me and I can get new speed thrills from a single e-retail purchase. I at first was attracted by the Talaria XXX and Suron...

    Madsen cargo bike BBSHD kid hauler "Bucky the Bumblebee"

    Yes it can get up to ~28-30mph with the 46t front 11t rear gears with just a rider, even with the 20" rear wheel at WOT. That comes in handy at intersections and little else as speed obviously not really the purpose of this bike. It actually handles very well at speed, and being able to quickly...

    cell_man Li-NCM triangle packs, two sizes now

    I can't say enough good things about this pack for my needs. Having nearly a kWh in the triangle of a safe pack has spoiled me quickly. There have been a few other people popping up on the forum showing off their build and satisfaction, and there has got to be lots of silent happy customers...

    How do you deal with theft of ebike parts?

    I have that battery, and I had to make it as secure as I could as it is used for grocery shopping. I wanted to build a secure in-frame box for it, but since that would've delayed me being able to use the bike I opted instead to make a Sheath that provides a locking loop for the triangle pack. It...

    Question about mac 12T torque

    FYI, here are the 12T and 10T MAC data at 48V that Cell_Man sent me, as I was trying to guesstimate performance since ebikes.ca simulator doesn't have slower BMC/MAC. I have always been told Mac 10T = BMCV2 Torque, but I was surprised that my 10T on cell_mans 14s9p NMC pack was much...

    cell_man Li-NCM triangle packs, two sizes now

    Well said qualifier for why this pack would be desirable for a builder. I do not have quantitative data on my triangle pack performance, but it has wowed me so far with its quality and practicality. My reasons for being happy in choosing this pack over Ping, Sunthing, OSN, Cell_man A123...

    Popstar’s MXUS Dahon and MAC Fisher

    10T MAC kit with 14s9P triangle batter on Gary Fisher build steps The build is more or less complete, now that I made a battery locking solution at last. Here is the latest picture of it: It certainly is not a unique or spectacular build compared to many of the impressive rigs being...

    I am almost finished with my build using this pack and will put more info in the build thread soon http://endless-sphere.com/forums/viewtopic.php?f=6&t=49099 including the lockable battery harness. Here is a picture of the triangle pack below my sideways 16in Gary Fisher Frame. You can see...

    Brake and Shift Cable housing and routing question

    Thanks for the reality check everyone! The problem was the terrible Bell cables and housing with too much stretch and friction. I didn't go cheap for the MAc and battery, but I almost went down old habits to be cheap... nope not this time... going to learn as I go and do it right.

    Brake and Shift Cable housing and routing question

    What shift/brake cables and cable housing are people employing when ebike modifications render original routing ineffective? I am working on my Cell_Man 10T + triangle pack with bag install. The triangle bag interferes with the shift/brake cables. Also I am upgrading my Gary Fisher Hoo Koo E...

    Any folding bikes out there?

    I have a brief run through of all the parts used in my mxus dahon folder build thread:Popstar’s geared MXUS Dahon Folder If true carrying while folded is a requirement, put even more thought into battery choice then other e-bikes. My headway 36V 12ah is as bulky as a A123 20ah so you really...

    cell_man Li-NCM triangle packs, two sizes now

    For anyone for whom the pack shape pictured above doesn't quite fit, Paul is telling me he is trying out a longer slightly shorter shape. I have a pack on order. The discharge C rate and the cycle life are my biggest worries for this pack over the 20aH A123 packs. I'm hoping though that the...

    Need help designing triangle pack, 18650 cells.

    Cellman now has a Samsung 18650 14S9P NCM triangle pack on his site: http://em3ev.com/store/index.php?route=product/product&path=35&product_id=123 It seems impressive that can get 48V 18ah inside a small triangle, maybe even a larger full suspension. I have a pack on order along with a MAC...

    May 2013 update: I'm adding my 2nd build progress 1st Build: mxus folding bike I’ve been riding this e-folder bike since August, but only now am getting around to making a build thread.

    I'm a noob and I wanna go sensible speeds reliably

    FYI, Mac is a geared hub hub motor that freewheels. I am moving to the MAC 10T soon, after getting my ebike feet wet last summer with cellman's geared mxus e-assist [which sadly he stopped carrying. He says he will be offering a new mini-geared option soon] on a folding dahon. -Popstar

    Watch out for train tracks... i wrecked...

    90 degrees only, 90 degrees only, 90 degrees only. I was riding in downtown Portland with my father-in-law from China as he rode my electric dahon . I pointed to this sign as we approached streetcar tracks: Luckily it didn't need translation into cantonese as he avoided the rails, but...

    Thread for new battery breakthrough PR releases

    In the Ga-Al alloy case I mentioned, the Ga doesn't prevent the Al2O3 from forming (AKA oxidation of aluminum), but instead, prevents it from forming the oxygen impervious layer and therefore accelerates Aluminum oxidation . Hence you can continue to react water with Al to form H2 (= fuel cell...

    Thread for new battery breakthrough PR releases

    Sorry for making this my first post on ES, as I have learned so many new things on the forum about motors and batteries for 10 months, but this subject is close to my profession and also some of my pet peeves: real science with potential, that is easily mistaken as a magic cure or a hoax. The...
