Zotto created the thread Finding High Power Lithium-ion battery Chargers.
" Hi all, I am trying to look for a lithium ion battery charger that will be able to charge my 100V nominal LMO lithium-ion battery safely and quickly. The battery is for an electric motorcycle conversion I am building, and I have been looking on the internet to see what other E-motorcycles have used, and I am getting a bit confused by some solutions I have seen online which use a constant DC output which is not correct when charging a lithium ion battery chemistry.

Does anyone have any experience in this, or know where I can find high power (2-3kW) chargers for my 100V pack? Any help is appreciated! "

" Keep us appraised on your progress.

One thing I learned from that Stepcraft unit above is that you really need a solution which can take the entire g-code script onboard at the start of the job rather than relying on the PC to provide the code execution line by line as the Stepcraft does - any interrupt on the USB and it drops steps which makes for significant issues on longer projects. We started looking into using an Arduino based 'server' to act as a g-code executor for it rather than relying on the USB but never really progressed from there and it's just been sitting unloved for a long time now.

" An old buddy of mine, Dave Harte, had a Sears Gilera Attachment 8119
Of coarse it was cafe'd and painted racer orange! I'm sure he probably still has and rides it on occasion.
He used to duct tape a piece of magnesium to his boot to shoot sparks down the road at night by dragging his foot... until the popo pulled him over for a safety inspection!! LOL "

" I spent my teenage years obtaining all of my motorcycle information from the bi-yearly Sears Roebuck catalog that was dumped on our driveway twice a year. After checking out the women's underwear section, I would immediately move on to the motorcycle section of the catalog. The first time I ever saw a motorcycle designated as a "scrambler" was in the 1959 catalog. According to a fellow that I know who actually owned and raced an Allstate (Puch) 250cc Scrambler, those bikes were the real deal at the time and were quite capable of wining races. Unfortunately, apparently they were a little too hot for Sears' typical catalog customers and that Scrambler model was dropped by Allstate within a year of being placed into the mail-order market.

One thing about the Puch bikes that took me 40 years to discover was how they could have only one combustion chamber and yet have two pistons. I give the Austrians credit for designing a "split-piston" single, but that didn't help Sears sell all that many motorcycles and a few years later they gave up on catalog motorcycle sales - although they did give it a try in the late 1960's, trying to follow in the footsteps of the Japanese, without much success, again. And now where are they? "

Nor did, I suspect, anybody outside of the immediate environs of the Perica Garage . However, the only Japanese bike I ever even remotely considered "Cafe-able" was the RD350, which I did, in fact, blueprint and cafe. That said, yes, there have been a whole raft of pretty amazing cafe bikes built in the last years, including this Guzzi (what I think is a) factory build I saw last night:

Attachment 8117

I disagree on the "Scrambler" concept. I think it's a pretty specific build, rather than a pile of whatever you can throw at it, but that's just me. I DO know that THAT ain't no scrambler! (Or as we say in Boston, THAT AINT NO SCRAMBLAH!) "

" It's funny Ted, the other night when I posted, I did a search for scramblers and that Triumph image is the "THIS is a Scrambler"photo I picked to post too, then I got lazy and didn't post it.

This is my ICE Daily Driver, I call it a Cafe Racer:
Highly modified Honda 400 Cruiser originally, chopped and lowered to make it more of a street racer. That's what the roots of Cafe is to me, whatever bike you can get your hands on, lightened and modified to go as fast as possible. This one will do 130km/80Mi per hour. It's actually been modified more since this photo was taken, and I gots plans for more new stuff this winter too. (nervous to try a Ton run until I upgrade the suspension)

I think of a Scrambler as whatever bike you can get your hands on, modified for off road riding. High suspension, flat seat that doesn't get in the way when you are standing on the pegs, knobby tires. The Cafe Racer of off road, the DIY Dirtbike that you can ride on the road to the trails, and then straight onto the dirt. A precursor to the Dual Sport really.

Here are several bikes that clearly predate the SURU that I would say are worthy of the Electric Scrambler title:

https://images.summitmedia-digital.c...photo-1200.jpg
In fairness, the one on the right in this photo is more of a dual sport.

I agree with Frodus about the SURU. It's a boxy over-sized electric bicycle, with silly Chinese rear motorcycle shocks that look totally out of place, and what appears to be about an inch and a half of front suspension travel (a measly amount for a mountain bike like 15 years ago, let alone a 2018 'Scrambler'). It looks like it was designed by Spongebob Squarepants.

If folks want to go out and design a new electric bike or motorcycle, that's awesome, and I applaud them for that. But, don't pretend that your creation is something that it is not. This is a capable but chunky electric bicycle, priced at about market fair value. It's a funky electric bike for on and off road cruising. I don't think there is an off road motorcycle enthusiast in the world that would agree that this even remotely qualifies as a scrambler. Also, a 10 second google image search will show you that it is clearly NOT the worlds first electric scrambler, so why is dude trying to steal that title. It's just bullshit. Play to your strengths, don't try to pull the wool over peoples eyes, they will call you out. "

" We never limited Cafe bikes just to Ducatis only. An example of an exceptional Cafe bike could be a modified Honda 400-4 Supersport, or any of the Honda 4 cylinder supersport family could be cafe bikes with the right handlebars or clip-ons, 1/4 fairing, solo seat, rear sets, exhaust, carb and suspension mods, drilled out everything! We've come along way since the 70's!!

There would be any number of different make and model cafe bikes parked at the Rock Store or Newcomb's Ranch every Sunday morning. Some of them were amazing too! "

" I grew up in the 1960-70's (I'm an old fart) and I always thought a cafe racer was any street legal "race bike" modified from anything... anything goes... no modification restrictions whatsoever. When I think of "scramblers", I think of Hare and Hound Enduros (sometimes called Scramblers) of yesteryear. The kind of races Steve McQueen is famous for, and my good old friend Roger Langevin used to compete with. Those were the days! "

" Oh for the love of ****.

It's not even remotely reminiscent of a scrambler. What a load of shit. It's also ugly as ****. There are also several other bikes that have been around for years that are just like it if not better. Stealth, for one. https://www.stealthelectricbikes.com...h-b-52-bomber/

THIS is a ****ing scrambler:

"Created by international award winning motorcycle designer Michael Uhlarik, the SURU Scrambler aims to expand the potential market for powered two wheelers. “There are so many people who love the look and feel of cafe racer and dirt tracker style motorcycles” observed Uhlarik. "

First, Michael of all people should know better, but I've had my issues with stuff he's said and done with Amarok. (He's been nothing but a perfect gentleman to me, though. But shit, Mike, just stop it.)

Second, if I hear some numbnuts refer to almost anything they want as a "cafe bike" I think my head is gonna essplode. "

" In Europe if there is a hidden defect - a part lasting much less than you can reasonably expect - then you can make the dealer pay for it, and the dealer then turns against the maker. I'm sure that there must be something similar in the US - a company can't advertise for a premium, 500.000 miles vehicle if it has such a short lifetime.

I can't replace it myself (the part is quite expensive), so i'm counting on Zero (i can't imagine they validate that they are making 12.000 miles bikes. If it is the case, they'll die very soon) and on my insurance (they will do the legal process, and they already discourage from buying Zero). In the meantime i'll have to buy another bike. "

It's also NOT a Scrambler, That part is apparently "marketing" too.


It's the world's first Electric Scrambler in the same way the Rumble is the world's first Electric Cafe Racer. "
