eBike news and items of interest

Greg that's an interesting video. 9 kw equals a touch over 12 hp. That 12 hp when driven through a proper gearbox in small motorcycles, less than 250 lbs., often result in top speed of mid 70 mph. I too am an e bike neophyte and can't speak to his e-motive components, but that frame and bicycle running gear are a bad joke. If he intends to continue "lift's of the wheel" and runs 40 mph plus daily he should spend some serious effort in strengthening the frame and upgrading components. I don't dislike his build, but I fear it's fundamentally unsafe at high speeds.
I've run two of my I.C.E. bikes well into the 70's, momentarily, on a couple of short pulls and got away with it. I re-packed the bicycle wheel bearings a few days later and all was good, but there wasn't a lot of lube remaining on the bearings and races either and that taught me a lesson. [My test runs were not on public streets, but were conducted on an airport apron, wearing safety gear. I also had observers & help in attendance during each of these pulls]
The old board track racers did much and fast on early bicycle technology, but compared to our steel, rubber etc. the stuff they used was greatly inferior and many racing injuries & deaths resulted. I'd advise against motorcycle speeds on bicycle tech for the streets. Organized racing on closed tracks deals with a whole different level of bike preparation, advanced skill sets, rules and safety equipment. all directed towards a dedicated purpose, safe racing, and shouldn't be confused with everyday riders and riding.

That's about a 30 mph bike. That's all the frame is good for. Think about the forces involved taking a curve at just 50 mph with good street tires, and a car on both sides of your bike.
 
I agree, I ride my bikes at 30mph and below, normally at 25 to 26. I've had motorcycles of all types and sizes, now at my age I like to enjoy the sights rather than flash by them. 40+ on a stock bike is not for me.
 
Why can't more e-motorcycles look like this? It was cobbled together by some ex-employees of Alta, the e-motorcycle company. I'd ride the snot out of it.

That's me too. Motorcycles all my life, but my fatty is a 26 mph bike, and I have just as much fun riding it as any other bike I've owned.

I just came in from running errands all morning on my 48 v.1 KW fat tire & I'm really enjoying it and my 36 v. 500 watt mountain bike for daily riding. Since I'm new to e-bikes I'm just enjoying the ride, but it's been all positive with both hub motored bikes.

Because the dirt bike looking frames are cheaper to manufacture. The sheet metal frame and battery box are one thus saving added expense of a custom box. It could be built however the problem lies in design, making a frame with all the features of current ebike frames with curves like a fat bottomed girl.
 
Been riding my new ebike for a bit, don’t think I’m gonna go back to gas bikes... just sayin’. Night riding is cool!

My fast charger already got smoked probably in the bridge rectifier, gotta fix that, ended up putting 5 laptop chargers in series for a 6 hour charge just to keep me going. I get about 30mi range and use my regen brake 95% of the time.

I added a front e-hub to one of my China girls and really like the hybrid experience. My fatty's getting a 48 v. 1 K. rear e-hub to make an all wheel electric with double lithium packs and separate controller. I'm loving it on gravel and dirt.

Yes I am thinking of adding a front hub. Looking forward to having regen in the front as well. Would like to do a hybrid someday but then I ask myself, why??

My profession may soon be eliminated or dramatically changed by new electronic advancements. Fortunately, employers will always need people that can solve problems and maintain the electronic equipment.

Schwinn built one for the military years ago the could be pedaled,, that one is a motorcycle.
I'm on my second ebike which cost 1/2 what the first one did & out performs it though it does
not come with fenders or a rack. While I am 71, the new bike is making me stronger, It
challenges me to pedal more & use power less. Basically, it is a mtn. bike with a motor,
not quite as fast as the other one, but made to ride any surface & has greater range with
a smaller battery.
In addition to the charge bar on the display, a second bar moves cross the screen to
show how much juice you are using. The challenge is to keep that bar as small as possible
or even eliminate it. Doing so increases one's range as much as one is willing to apply
oneself. It has a very standard 48-38-28 chainrig & pedals well on the 28 without power.
In spite of the name, it's German,( the company names it's bike's after cities.) This
happens to be Moscow which maybe why I got it so cheap. I don;t think U.S. sales
have been too strong. :) From black friday to new year's they were $1099, I paid $ 1299
in Oct.

Comes in 29" or 27.5", 13ah or 16ah, top spd 25 mph, 'genuine' range 30 to 50 mi. or
whatever you make it. The price leaves wiggle room for customizing. Very comfortable.
The fat bike version is called Aspen,(trite) same price. Another outfit bought a bunch,
painted them gray, changed the name, & hiked the price $300, I love this bike.
