The other day I got an email the other day from my good friend Larry at Boxy Bikes who sprung for one of the new 72v 11.6ah PF packs from Lunacycle available for $599 with a charger here. Eric’s 72v battery is pretty amazing. When I took off with it the first time I actually felt a…
I’ve been in the process of building a 14S7P 18650 GA 50 Amp Cont soft pack for some time now. In the process I’ve learned a whole lot about battery building and exactly how challenging it can be. Once of the real struggles I’ve had is finding a decent battery spot welder that doesn’t break the bank.…
Whether you’re in the market for an 18650 ebike battery pack or you’re thinking to build one from scratch one of the big decisions you’re going to have to make is whether you’re going to go for a pack that is glued together or one that uses plastic stencils to keep the batteries together. There…
With modern 18650 cells almost without fail, every problem with your battery which is NOT caused by improper mounting and physical damage to the battery is going to be the BMS. The BMS handles the charging and discharging of your pack making sure that there are no problems with any of the cell groupings. When a…
I had been itching to do a full suspension electric fat bike back when I first started this blog several years ago. The bike I had my sights set on was the $1500 Bikes Direct Quigley which promised a full suspension frame, X9 derailer, X7 everything else and a Bluto front fork. I knew there was no…
When I first got started in the ebike thing, what I really wanted was a tiny 7lb battery that I could throw in a backpack and ride for 90 minutes in the woods with. After a lot of experimentation what I ended up with was a 16lb battery that I kept in my backpack that…
A year and a half ago I read this article on fat-bike.com about the up and coming Juggernaut Pro 4.0 tire which promised to revolutionize the fat bike tire market. The new Juggernaut Pro tires had a pretty deep tread pattern but at less than 800 grams, were much lighter than any Fat Bike tire…
Not even a year ago I would throw my huge 12Ah 16lb LifePo4 Prismatic battery in my backpack and head out to ride in the woods for an hour or two. Although I had experimented with the ultra-light Hobby King Lipo’s they simply had too many downsides to feel safe strapping one on my back…
I tend to be extremely wary of most Kickstarter e-bike projects, and over the last several years there has been a lot of them that have come and gone. One project that has got me pretty excited is the new GeoOrbital wheel that showed up on Kickstarter 2 days ago and already has over $200,000 in…
I have yet to do an article on a BBSxx display because frankly I’ve never been moved to. I did a short article that describes the differences between the many different kinds of displays here, which has been one of the more popular articles on this blog. I’m quite certain that Bafang does not actually…
