Heavy Hub Motors Can't climb hills.
Hub motors fall off the frames.
Hub motors are not efficient through out the whole range.
Hub motors break short spokes easy.
Hub motors unsuspended weight gives a rough ride over bumps.
Basicaly hub motors suck amps.
Hub motor users are in denial.

Oh STFU already. Everytime you come into a thread you ruin it with your hill climbing anti-hub motor bullcrap.
Honstely, STFU and let the people with hub motors enjoy the subject at hand: ie: eBike videos.

I don't want to get caught up in the argument you guys are all involved in... I do want to complement the video though.
Another great video. I haven't watched the whole thing (I can't watch a video that long from work) but from what I've seen so far it's awesome.
The scenery out there is just amazing. I would love to go riding there. And your bike seems to be doing great.
Did you make this before ebikes were banned? I'm guessing they probably don't enforce that ban too much...
I can't argue with performance. It's just unbeleivable to me that you are doing this with a home made motor on a Huffy! Excellent work man.

My mountain bike videos are right here. (http://www.petefagerlin.com/video_gallery.htm)
That boring, tame, slow riding on a smooth dirt roads does not prove that "a center mounted motor ebike can take as much abuse as any other bicycle on dirt roads or trails as long as the batteries are mounted securly(sic)."
You obviously aren't at all familiar with how much abuse other bikes can take nor with what kinds of trails mountain bikes can be ridden on.
Not to mention the additional loads that a motor and batteries would place on the frame if it was ridden on some challenging mountain bike trails.
Its been explained to him before, but he's not interested in listening and either doesn't seem to understand for himself or doesn't care. I've given up providing fact and explanation to him, as he's only here to troll.
That rockville video is pretty good. I only had time to watch that and the ride through Fort Bragg. Fort Bragg looks like a nice quiet enjoyable run too, though some of those switchbacks and narrow entries could be deceptive. Nice videos!
I'll hopefully be able to borrow some kind of recording device this winter, as we've got a plan lined up for some winter riding in December.

All Randy/Randall (or whatever this guy's name is) has to do is make his frankenheap available to someone who will take it on an actual mountain bike ride in Poli Poli, or a Skyline/Poli Poli combination and his crazy claim about it being able to "take as much abuse as any other bicycle on dirt roads or trails" will be disproved quite easily.
Been there done that several times.
EbikeHawaii
11-20-07, 07:54 PM
LOL!
Pay close attention to this part:
"his frankenheap available to someone who will take it on an actual mountain bike ride"
Putzing around on dirt roads does not count, nor does it substantiate your ridiculous claim.
Comments from your lame video like "no bike could go beyond this point" and "I come up this but there are too may rocks to skid on" (both paraphrased) only prove that your "mountain biking" experience is incredibly limited.
If your frankenheap was actually ridden on real mountain bike trails, at normal (not grandma) speeds, it would be in pieces.Thats what they said about my 68' AT3 125 enduro I 7 ported and converted before the Yamaha YZ 125s were a reality. I won several MX races in Calif and this one at the old fairgrounds in Mauis 1st motocross race in 74'.

Non sequitur.
You have provided ample proof that your claim that your frankenheap will "take as much abuse as any other bicycle on dirt roads or trails" is utterly fallacious.
If your frankenheap was actually ridden on real mountain bike trails, at normal (not grandma) speeds, it would be in pieces.Try going 20 mph up hill on the dirt with any mountain bike or electric bicycle. Your mixing apples with your lemons.Don't get mad at me because you have a piece of crap bike.lol

You have claimed that your frankenheap will "take as much abuse as any other bicycle on dirt roads or trails."
That is utter crap, as I and others, have irrefutably demonstrated.
You have also refuted your own claim (via that boring, tame, slow riding on a smooth dirt roads video where you talk to yourself incessantly) and additional demonstrated that your definition of "mountain biking" is a grandma's definition of mountain biking.
What an odd thing to post. First, I am not mad at you. I pity you. There's a big difference.
Secondly, you have a frankenheap, I point out that your claims are mere fantasies so that somehow means that I have a "piece of crap bike"?
How exactly did you arrive at that conclusion?The same way that you came to your conclusion.LOL
EbikeHawaii
11-20-07, 09:00 PM
No, I came to my conclusion by understanding that adding tens of pounds to a mountain bike frame (even one that isn't a POS Walmart bike) makes that bike less resistant to abuse. Then I saw the video of what you think "mountain biking" is and I understand that what you describe as "mountain biking" does not even come close to being representative of the forces that mountain bikes encounter when they are ridden on real mountain biking terrain.
So yes, your claim that your frankenheap can "take as much abuse as any other bicycle on dirt roads or trails" is absurd.
How exactly did you come to the conclusion that my very durable bike that has actually been ridden on very diverse, very challenging terrain in a number of different states and countries over a number of years is a "piece of crap" again?Downhill racing on a human powered mountain bike is a far cry to what electric bikes are all about.Neverthless a 45 lb Huffy with a 12 lb motor/battery system will win any round trip races up and down the same hills on round trips.
I gave up racing for pleasure and riding safley and the cheap Huffy fulfills my needs to go anywhere and faster on round trips up the hills and back.I do NOT rely on pedaling at all. Your jabbering pure nonsense about something that does NOT apply to ebike riding..Your application is purely downhill bicycle foolishness.Even though a Huffy with good wheels will handel the same abuse.Show me a video where your expensive pedal power mountainbike is going up hill on a good grade at 10 mph yet at 20 mph the Huffy does fine if you don't mind your kidneys getting jared.Of corse a expensive bike will work better but who needs it when the motor and batteries coast enough? All you really need on a ebike is a strong frame ,wheels and strong lightweight efficient motor system with reliable brakes.

11-20-07, 09:49 PM
I am not referring to downhill racing. I'm referring to actually riding your frankenheap at mountain biking speeds (not granny speeds) on mountain bike trails.
After all, you're the crazy guy that claimed that your frankenheap can "take as much abuse as any other bicycle on dirt roads or trails."
Mountain bike trails can be quite different than the smooth dirt roads that you offered up as "proof" of your frankenheap's durability.
What does that have to do with your silly claim?
Furthermore, that is pure conjecture on your part. I would take that bet in a heartbeat on many trails. This one for example:
http://www.petefagerlin.com/p7hg_img_3/fullsize/bp2_fs.jpg
Not only would you be walking your frankennheap up it while I would be riding, you would be walking your frankenheap down it (assuming it was still in one piece of course, which is a big, big assumption).
So you frankenheap can take you "anywhere" now?
Again, as your silly video demonstrates, that is a lie.
How is pointing out your silly assumptions ""talking nonsense"?
You forgot to answer this question:
How exactly did you come to the conclusion that my very durable bike that has actually been ridden on very diverse, very challenging terrain in a number of different states and countries over a number of years is a "piece of crap" again?We are talking EBIKES! What ebike do you know of that will take even ONE bad spill and continue to work without collecting all the batteries on the ground let alione the motor if it is not in a strong frame and protected along with all the wires and cables?? This is a ebike forum is it not? Even My Huffy will climb up rockey hills much faster than you can pedal.You have nothing to support your BS that your bicycle is made any stronger if that is why you like to argue about and either do I except for over 25,000 miles of hard use.It is YOU that is making the silly assumptions.My knowlege is from riding both expensive bikes and cheap Huffy bikes for many years.

No, you're talking about a comparison between your frankenheap and any other bicycle.
You: "take as much abuse as any other bicycle on dirt roads or trails"
First, I'm NOT defending EBikeHawaii for his remarks as he is prone to hyperbole, but EBikeHawaii is correct that THIS forum is for E-bikes. Furthermore, the types of off-road trails that an E-bike user would normally cover is much more in line with the "grandma" style of riding than your outlandish examples of mountain bike trails. Yes, I do realize that the two of you are living in entirely different worlds... ;)

Just to confirm, can you quote a source other than yourself for the "world's EV record climb to 10,000ft" ?
I'm not seeing this anywhere. No guiness record, no wikipedia article, no sports sanctioning body article. Nothing!
The only hint of an EV world record in a hillclimb was the Pikes Peak climb.

Why are you avoiding the question?
Your "record" is official isn't it? So point me to the "official" recognition of the record so I may enjoy it as well.
Or is your "record" just a bunch of B.S. ?
Personally, I think it's real. After all, why would someone go around bolstering about such a claim in this day and age? You'd have to be quite stupid to go around claiming to have a world record which can't be proven. Right?
But I really have to wonder why you keep avoiding the question? Why can't you show me which sanctioning body reconnizes your record? And there's surely a nice article to go with it that I'd think is worth reading.

I think you were right on your first thought.
Randy looks years into the past to make his mark on the world, and even his self proclaimed world record isn't much to write home about since there are no other challengers! (unless you count the Team Mavic riders that beat him to the peak with only pedal power)
If it's a "world record", shouldn't it be in the record books somewhere?
I'm not saying Randy's achievement isn't worthy of recognition. But I am saying that his sol called "world record" seems more like a self indulgent claim than a fact. And it just goes to show what kind of character, or lack thereof, Randy has.
Too bad really. Too bad he can't bring his bike indoors too; his head doesn't fit through the doorway.

SUN CYCLES
Randy Draper, a longtime Napili, Maui resident and tour boat captain, has been experimenting with and inventing ways to harness solar energy for years. In the 1980’s Draper outfitted his house with solar panels and a small windmill; he hasn’t paid an electric utility bill since. Realizing the potential of the sun’s energy, Draper continued experimenting, at one point crossing the ten miles of ocean between Maui and Lanai on a catamaran powered only by solar energy. It is only fitting that his most recent achievement was climbing the 37 miles to the top of 10,000 foot Mt. Haleakala, which means “house of the Sun,” on a solar powered bike. Haleakala boasts the steepest road in the world based on vertical climb over distance. Draper chose the annual “Cycle to the Sun” race to test his bike. After starting at the rear of the “human powered” pack, he reached the top of Haleakala in little over three hours, at an average speed of 12 miles per hour. Draper, whose vision is millions of clean, efficient, and affordable solar bikes being used as transportation worldwide, is in the process of pitching his technology to prospective manufacturers and investors.

If this is not a worlds record then tell me who has done better in a ev elevation climb.Who has even made a 6800 ft climb in a EV or on a electric bike? Possibably 2 worlds records here that are documented by a race staff and published. I also have Video documentation of these rides using a single set of batteries and a single charge that was done at my home from SOLAR Power only.. WITHOUT the use of lithium batteries.
I still don't see anything ressembling a world record except for you spewing your self indulgent claim.
The problem with your "world record" is that you don't know if it's a WORLD record. Sure it might be the EV record at that site but there may be someone else in the world that has driven an EV up to that height much faster than you. The electric car that climbed pike's peak would surely beat you to the top of that 10,000ft mountain assuming its got enough battery to make it. Trouble is: you can't claim a "world record" because nobody officially reconnizes it as such.
So here's what's going to happen:
RANDY'S WORLD RECORD CLAIM IS FAKE
Until such time your "record" is reconnized, we're just going to have to call B.S. on the whole claim.
Too bad really... too bad your obnoxious self serving personality is getting in the way of advancing EV technology. You're so full of lies I just can't trust your claim of having a better motor than anyone else.

The road I climbed to the top of the Haleakala is the highest accent to 10,005 feet in elevation in the world in 36 miles or less on any road from sea leval.

I totally agree. After all... I'm the guy who started this thread.
But go back to post #18 where Randy suddenly jumps in with his self proclaimed record once again. This combined with his arrogance and his complete hatred of hub motored eBikes is dragging down this forum.
This isn't a place for his self promotion and fake claims.
You want to clean this forum up? I'm all for it. I've stayed away from Randy vs. Lowell discussions for a long while but Randy's arrogance is really starting ot hurt this forum. Your best bet at this point is to get Randy in line or ban him.
sure you could ban Myself, Lowell and any othe people than Randy has rubbed the wrong way but what is it going to give you? Nothing much until the next guy comes by and gets pissed off at Randy for his crappy attitude.
I'm sure there's some good in Randy somewhere. But lets face it: someone needs to put him back in his place at teach him a little bit of modesty. If I were a moderator I'd do it for his own good and that of the forum.
That being said, I'm done with Randy. I'll just talk to other people instead. Hmm... I see a "Bionx first ride" thread which I could contribute. Hopefully Randy hasn't sabottaged it. ;)

The 5303 is a high speed hub motor, and has a higher no-load speed than the popular 5304. It will handle as much power as any bicycle sized batteries can dish out, and makes hills dissapear. 40+mph up a 10% hill :)
Here's an old video of a standing start on a 4.25% hill. 0-75km/h. This is an old configuration with a front fairing, and I would regularily pull 80km/h up this hill on my way home from work.

The bike is a Rocky Mountain frame with every other part upgraded.

Nice videos, nice setup. I'm jealous of your Vancouver weather, Lowell!

Fun! This vid is much louder (wind noise) than the behind fairing mounted camera vids that you posted in the past. Was there an appreciable drop in efficiency/range without the fairing?
The difference is very noticeable, and the bike loses at least 15-20% efficiency without the screen on my normal commute, and more at sustained top speed. The screen and 1/4 fairing were badly damaged when someone (not me) laid the bike down onto concrete. V2 fairing will be much better and hopefully faster :)

This may be a dumb question, but what's a fairing?

Something like this that helps lower the overall aero drag of the bike. http://www.zzipper.com/
It takes rougly 1300W to propel a mountain bike at 35mph (a fast TT pedal bike speed). Switch to a triathlon bike and you only need 675W to go 35mph. That's a massive gain in efficiency, and certainly more than anything that could be gained electrically on an ebike.

"Depending on the exact configuration of the bike and the tires you are using, the power consumed by air resistance and the tires rolling resistance is typically about equal at 9-12 MPH. But because the power to overcome rolling resistance is linear with speed, and the power consumed by air resistance is a cubic function with speed…by the time you get to 20+ MPH typically over 70% of the overall power you deliver to the pedals will be consumed by air drag!"

First test of my new helmet mounted camera.
X5303 power in a 20" wheel hit 78km/h on this ride. The overpass is perhaps the biggest hill in Richmond...

My goodness! Almost 50mph on a bike. One pothole and your bike is toast. I think 30 mph is the max speed I can comfortable ride all the time. The occasional 40-50mph is ok. I think that 30 mph is fast enough for me to get down most narrow stretch of shoulderless road before a car catches up to me.

How fast can the average person pedal on flat ground with no wind? Say a mountain bike with 26" tires. How fast could the average person expect to pedal, going as fast as they can, on flat ground, with no wind?
I have no concept of what 30 MPH (or any speed, for that matter) actually looks like on a bike. I wonder how fast I can actually pedal?

Well, at some point John Forester measured the speed of all the cyclists who entered Ames Aeronautical Laboratory at the start of shift of a normal work day. The location was an arterial street with bike lane, substantially level, and at a time without wind. The average speed was 16 mph, the 85% speed was 18 mph, the range of speeds was 12 mph to 22 mph.
If a non cyclist gets on a bike and goes flat out, I'd guesstimate they'd end up around 25mph or so within a few secs, and then peter out. At a sustainable speed they're maybe around 10mph? Riding around, cars in my neck of the woods appear to expect bikes to be going ~15 mph regardless of my actual speed. Someone going 20mph up a reasonable hill looks like a superhero, and 30 mph on the flats looks really damn fast.
