Where do I find out more about what Lyen offers? Do they offer a 72V model? thanks!

Yeah, it's not easy...I hope I remember how for my next upload.. :roll: Nice looking bike/rig... I was wondering what you did to upgrade the brakes? I have a similar situation w/my brakes. Also, it may be good that you don't have disc brakes, since your hub motor doesn't (I don't think...)...

The Chariot Skates look awesome. And electrification is definitely a possibility...they look like half-Segway/half-humans. Bravo! thanks for sharing :D

There should be no problem feeding a 408/4011 30 or 40amps :D Keep us posted!

I don't think this idea has been thrown out there, but how about a dual-speed hub like a Clyte 408/4011 or 4012 with the dual speed controller? Not sure about sources, but i think they are available... somewhere :? I believe you use the 408 for normal cruising and switch to the 4011 or 4012...

I think it's a valid point. In MN there are 2 things on the books (as far as I can tell): motorized bicycles - which are basically watered down motorcycles- and electric-assist bicycles. Still trying to get to the bottom of the latter, whether it needs to be registered, some deal about brakes...

You're right, my bad. The description of the lights runs right into the dc-dc converter description, so I guess I thought (ADD? :? )a dc-dc was needed for Justin's design. They are not. One thing I've had diffictulty finding with any tail light is a way to mount it. Nearly all of them come...

Excellent job, Y ! Your hard work has paid off, I think. At least it gives us amateurs some insight into tearing into an EV system and understanding the workings....Much thanks for your leadership! Overall, do you think it's better to just buy individual cells and add a different BMS? Or start...

I wholeheartedly agree. I think tail lights are the current weak-link in the ebike lighting chain and often feel like a moving target when I'm night riding... FWIW, here's another option for those not wanting to smt solder...Looks a lot like ebikes.ca's but includes the dc-dc converter. Stil a...

Ypedal... another question on the video (not pack related...sorry): Your throttle appears to have some kind of external sleeve thing that you're using as a cruise control. What is it? My thumb gets tired on my throttle and I have been contemplating something like this... Please inform --unless...

Nice work. Cool video. The only thing you need is a beautiful assistant :D Funny to see the cars just barely passing you. My guess is that you were going about 35-40mph...close? Keep info coming on these packs. Look like a great product at a resonable price. ... group order anyone?

Thanks, I'll give it a try. Seems like batteries, more than anything else batteries are the weak link.... Then again, if we had super powerful motors (room temp superconducting...?) then our existing batteries may just be awesome :D

Some interesting stuff. "10x storage capacity" Not sure if that means Ah, but it sounds promising...hopefully sooner than later... :? http://www.pddnet.com/news-news-storage-material-improves-energy-density-of-lithium_ion-battery-110209/

Yes, she is quite lovely... Sorry. Distracted. thanks for the info, and yeah Helmet Always. I oftendo a quick chk of the bike..but not always. Good info. thanks for sharing! :)

I'm sure my range is impacted, but I haven't pushed it that close to the limit. Am still able to do my 14mile round-trip commute on my 48V 16Ah Ping V2 without issue, even tho it's about 30+degrees F cooler here in lovely Minnesota now than in the summer. Also, no perceived power/top speed...
