Re: Electrom1 Long Wheelbase Recumbent Light Electric Vehicle

I've been testing the new molded carbon fiber front fairing & windscreen mount. It has exceeded expectations so far. it is extremely light and durable. There's lots of room for all sizes of rider and their different feet. The dome of the windscreen is a bit higher than needed so on the production ve...

Re: Best Value fast ebike for my commute?

I'm a pretty avid cyclist If you have some knowledge of bikes to go with your interest, then I would suggest either converting one of your existing bikes to electric, or buying a good used bike and electrifying it. If you are in North America then I would suggest buying a wheel kit from Grin Tech h...

Re: DIY Capacity test battery packs

I fully support the DIY approach, and I was going to do a similar thing. Then I found these discharge cells on ebikes.ca. at only $40 for a known quantity it seemed like a better way to go. https://www.ebikes.ca/media/catalog/product/cache/2/image/d33f8bafbb033e6f66b003faca9e0ee7/l/o/load68.jpg 6.8 ...

are you able to share more on the gear ratios from the pedals to the generator and pedals to the rear hub? Yes, as you surmised, the diversion of human power from the rear wheel to the generator is accoplished by a simple freewheeel. Once the vehicle is over about 12 kph the human energy goes only ...

Re: 3WD hybrid GO-4 project

I've had really good luck ordering batteries direct from Unit Pack Power in China. The batteries I've had them make for me were 72 V 20AH, I've gotten 3 and they've all been great. Cost per battery before shipping was $498 USD

Re: BBS02 powered HT commuter - Vitus Nucleus 29er

bummer about the BB spacing. If you're willing to commit you could take the frame into a bike shop that has a BB facing tool and get the BB faced down to 68 MM. It's fairly soft Aluminum so it should not be too difficult.

A few years ago I was riding the old version of the Electrom, and I took it over to Vancouver. While I was there I had the opportunity to have my friend Robin Coope take it for a test ride. Robin is an extremely skeptical person when it comes to recumbent bikes so i really wanted his opinion. After ...

Closing in on being ready to make the molds for the Electrom body panels. This is the front Foot-well and fairing support plug. It is now polished to a "class A" finish, now it gets four coats of mold-release wax, a misting of PVA Mold release, and then I make the mold. After that I do the polishin...

I’ve been putting as many test miles onto the new Electrom 1 frame as I can lately. My goal is to get the first frame up to at least 5000 KM of testing in time to make the next set of frames for our Beta backers. Here’s a quick bit of video I shot while doing early morning speed runs. There’s even a...

thanks. I like that tire. I'm running16 inch 2.75 Heidenau Moped tires and I have to say that one of the best things about the 20 inch bike wheel is that it takes 16 inch moto tires. I agree that geared hub motors aren't ideal, but they do allow folks in areas with lower power limits to play the gam...

So I understand the mechanical setup, but how do you use the motor as a generator, and how does it's output get turned into rectified current at a voltage that can charge the battery? From what I think I know, there would have to be field current in the stator to go from free turning to generation,...
