Is the controller still available? Thx

Oh my goodness, that probably costs as much as a car! ... but you probably use it instead of a car all the time, huh? ... itll probably pay for itself in gas/repair/etc savings within just a few years, huh? ... its probably all around more practical than a car for short-medium distance trips, huh? C...

Ok, so finally got to the clear coat. Onto preparing head tube: I was 1mm off, so I ordered a Cyclus head tube reamer. It's much cheaper than the Park Tool version, just took a week or so to get here. https://i.imgur.com/LPgTtkU.jpg https://i.imgur.com/Vf5y9AH.jpg Finallyyyy https://i.imgur.com/A3y7...

Yeah it is mostly an aesthetic choice; I wanted the frame to look like composite construction, more like carbon, instead of some kichy, gilligans island style bike. Bamboo bikes are really, um, cute, but I wanted something that looks just a tad more grown up. I think that doing an epoxy pigment with...

A lil progress for ya, should be assembling the bike by the end of this week! I got some new pedals and doo dads in from Amazon the other day so now I'm extra exited to put this thing together. Plus I can stop riding the bus to work... https://i.imgur.com/zVbbKrE.jpg https://i.imgur.com/CEiYUSN.jpg

Ok. Dumb question. Did you "regret" buying from BBro or Liion? Sorry. It is easy to confuse me. :oops: No such thing, I also get turned around quite easily. I regret spending a dime with battery bro, and i also regret not listening to my battery expert/friend’s advice, who recommended me ...

Many ppl add more solar when parked (stacked on top of each other while in motion) they just tend to use semi flexible mono crystalline panels vs thin film because of efficiency (>20% vs ~8%). But hey, itll work, and I don’t know of anyone else doing it:) if u wanna be first, use something containin...

Yea man i currently charge 0.00% markup on battery cells lol, but yes, being thorough is the only way 2 b. Honestly i was told by a friend to use liion before I bought thru BBro, one of the nerdier regrets in my life. Ever since i found this vendor corner I’ve been dishing some pent up truth about s...

Hi, kind of a niche-within-a-niche, but... I've found myself building bamboo e-bike frames, and have the capacity to make a few extra parts here and there for others who may be doing similar projects. Building one yourself is definitely the most affordable way to get into a top quality frame. The on...

This thread is officially hijacked... I simply wanted to draw attention that renewable sources of electricity produce the same quality of electricity that fossil fuels do. We should regard them as just as valid of an option for energy production as non-renewable sources, thus, they should be categor...

Also, even if you forget the travel aspect, I think LiGos are a good purchase because of the quality and thoughtfullness of the BMS and potting

LOL I got it from a company that promptly went out of business. Has anyone heard of what happened to 'bamboobikesupplies.com?' IDK, expired domain. I am talking with a local company (in Winston-Salem) who can provide hemp fibers, they're called American Hemp, LLC, and the guy's name is Patrique. Nic...

LOL I have never seen one in real life, but my friend built one and toured around the coast of Scotland with it. Apparently he only fell over 3 times haha. He wanted to use this bike for a Sun Trip, but they vetoed it due to safety concerns! https://www.thesuntrip.com/participants-2017/mickael-jogue...

After reading about the solar cycle analyst on your bike, I was able to implement it on mine. I haven't done a lot of miles with it yet, but I really like how much easier it makes things. Thx for the quality info about your build, it helps everyone out.

BTW your sun-tracking trailer could be in a tech museum, that rig is beautiful. Best o luck with the world tour, and please use my experience to avoid a similar one for yourself.

Great question - last time I flew over with a 48v, 7ah LiFePO4 pack in my F'ing carry on. I disconnected it, taped the terminals w/clear tape, etc, to make 4x 12v, 7ah bricks (each @84wh, the limit is 100wh per battery), but I still had to prove to the TSA as well as the airline that I was following...

Umm, ok, so there's a debate is here now, welcome to my thread, lets not get to 90 pages. Since you've given me no-thing besides hot air and 'gut feelings', here are some actual facts, found by scientists, and verified by people who have electricity in their homes in these respective countries. I'm ...

24v Lee Iacocca/ EV Global, 1997 model. https://i.imgur.com/AX65jO0.jpg Not a high performance bike, but quite a classic. I keep it around to test b/c I like the features it has, like cruise control, taillight integrated with brake cutoff handle, loud @$$ horn, very comfortable. It's got features th...

NOWHERE! - Does this company even exist, and do they want my money at all? How are you gonna sell me a complete motor kit that cuts off every time you use full throttle, or set the PAS to high? Come on. The battery included with the kit's high current cutoff was too low, such that whenever the motor...

Look, sorry guys, but I had a thoroughly horrible experience with Battery Bro, and will never order from them ever again. I switched to LiIonWholesale (https://liionwholesale.com/?refer1=adw&gclid=EAIaIQobChMIs4ir84a73AIVj4lpCh04vAZAEAAYASAAEgIdhPD_BwE), they ship in 2 days from VA to NC. We use...

And here's a link that explains how Midnite deals with this dilemma on the Kid MPPT

Sorry to resurrect this thread, but I think talking about the different applicable charge controllers out there is not a bad idea. Here's a link to a Morningstar page that shows which of their products are compatable w/lithium. Note that only some of them will run on a 48v system. https://www.mornin...

Yeah, I contacted Midnite Solar asking if they could customize a charge controller for me. They won't. Also thought about using an MTTP to 12V, then to an iCharger, with Parallel balance charging to the 4S packs. Some Midnite and Morningstar charge controllers can be programmed to work with modern ...

This build is progressing just like any other home-built bamboo bike w/unique geometry, so there's lots of info out there on the interwebs if you want more info about the particular steps we're taking. We CNC'd the frame fixture set (I'm told that the word jig is not ok to use in the south) out of s...

Where's the weeed at?

Oh, right...
