Watch out for train tracks... i wrecked...

practice riding in the street along side a curb parallel

now bunnyhop sideways up onto a curb/sidewalk

this skill will save you when you get stuck in a rut
but if course you have to feel you are in a rut

it is possible on a 60 pound clunker
up a normal size curb
on a regular bicycle you should be able to do it over a tennis net if you are young
not sure about a really heavy fake motorcycle ebike

When it comes to bicycles and tracks, I don't think it matters what kind of tires you're running. Those tracks just pull 'em right out from under you. There is a set here in Albuquerque that is right near a bike path. It has claimed many victims. I haven't had to face them on my e-bike as of yet. I did, however, have a close call over the winter. I was going through a curve at speed (28 mph), and there is a short bridge part way through. There must've been a little ice on the road, because both of my tires slipped for just a split second. I had panniers full of groceries, too. I sure am glad I have a front-mounted battery pack. Probably saved my ass that day.

Tires + a good suspension can save you in situations like that man i strongly disagree with you.A nice tier 2.35 and above can make a hell of a difference in situations like that.

I was saved one day ill tell you the story.You must have notice some large hard PVC outdoor watering tires that there are all around in parks and forests this days.So one day i run over one of this things without even having prepared my self for anything weird.The front wheel passed without any issue but the rear started spinning and the bicycle took a 45 degree left angle....i don't know how but i manage not to loose control and crash on the hard stone floor.

This thing was like two regular rail track's together :shock: it was so slippery and dangerous

Always wear protection gear mates and take care

Well, it's probably better than riding on a set of pizza cutters. Still, train tracks can even take down motorcycles. I didn't mean to imply that bigger tires don't help, but they don't make it a guarantee that you can just roll right over train tracks. Big tires, small tires, e-bike, motorbike... Train tracks don't discriminate.
 
Damb Neps! I was looking for my "da bomb" thread fix this week, couldn't understand why there were no new burnout videos, now I know. Sorry to hear it man! Wishing you back to 110% status.

Noooooo! Don't change your ebike trajectory. I don't think a 29'er will handle that either. That's an insane, inferior design of a railroad crossing. The guilty parties are those who angled the highway and tracks together at FAR less than 90 degrees. I'm stunned that they couldn't do better than that.

I know about this problem from when I was teeny tiny little - I grew up around railroad tracks and had the (good?) misfortune of doing this at a very young age on a 20" bike. Even so, I'm not so sure I'd have picked my way through this situation correctly: that's a seriously flawed intersection, not only for the way it tries to push the bike wheel, but how it increases the time both cars and trains are exposed to each other. Holy moly!

Thanks for posting on E-S: you've made us all a little smarter and safer. I'm with LFP, though: where's the carnage pics???

I believe it has to do with the feeling loosing the earth under your wheels.Suddenly all things start to spin :p.The hole experience is so overwhelming in order to loose control of the bicycle.I agree that there is no guarantee its all reflexes and luck.
 
Ah, i'm not one to post carnage, but once i get the bandaids off tomorrow ( not looking forward to that, because you know, arm hair ) i'll satiate your fetish :lol:

So i've regained most of the motion in my arms since the crash but there is still some soreness. My right hand hurts and the soft spots that got scraped hurt bad too. I think all my bones are in the right place still. I'm really thankful for that.

I'm still thinking 29er - you know why? this 'low to the ground' stuff i've been doing is not good for seeing train tracks ahead of time. I think i will be in Utah for at least another year. There are tons and tons of railroad track lines in downtown salt lake city and i believe i am going to get nailed again eventually out here. I am going to exchange some handling ability for the ability to ride tall 'n proud.

Plus i have always wanted an excuse to go 100% chain driven.

As for 'da bomb', i think i'll jerry rig up some really ugly but functional 2kW MAC motor mount just to get the damn thing tested, and sell the frame for practically nothin'.
 
The bigger (taller) you are, the harder you fall. :roll: Good to hear you are not broken anywhere.
 
I think it's funny, the very reason you're looking to switch from smaller more aerodynamic yet greater chance of crashing on obstacle wheels is the very reason my interest in riding single-track has been re-kindled. Roadbike 700c wheels with thin smooth tires are so sketchy on wet tree roots crossing trails and things, it makes it thrilling just to try to complete the trail at a reasonable pace without wrecking the bike and/or yourself. It elevates the chance of unexpected time spent brushing little bits of forest floor debris out of your knees dramatically over doing the same trail on a suitable mountain bike. This is what re-kindled my love for single-track riding, that experience of eating sh*t unexpectedly from obstacles that on a mountain bike with knobby tires and good suspension you can simply ignore and roll over safely. On 700c rimes at 100psi on smooth tires, you either bunny hop it, hit it perfectly tangentially to the contacting edge you need to climb over, or welcome to spending some time brushing yourself off and picking your bike up out of the bushes. I missed that part of riding, I hadn't had it much since I was a kid. Now I've got that unexpected crash at any obstacle thrill back again without having to go to exotic extreme riding areas and typically be at a gravity driven speed that involved serious injury prone kinetic energies from high impact speeds. On the road bike, I struggle to pedal along at 10mph most of the time, sinking into the trail floor deep (I think roadbikes might be harder on soft forest trails and soft packed dirt trails than dirtbikes ridden nicely!), then randomly and unexpectedly eat-sh*t on some 2" tall slippery root I didn't even notice, but my kinetic energy is so low at the moment of impact, it's a matter of laughing and getting back on the bike to ride away slightly more dirty than the previous wreck left you. :)

The wrong tool for the job is well proven formula to begin an unexpected enriching adventure. :)
 
Ouch never fun to crash on the tracks. Good you had your helmet on. Twenty mile an hour crashes are very hazardous to yer health and well being you are lucky you did not break bones. I did the same thing when I was young and healthy, jumped one track then another and then several came together in one place. Tire got stuck in between the tracks and I flipped over quite nicely with the tire and bike staying where it was. Me on the other hand rolling down the road and landing face up, several yards past the bike, with the rain spattering in my face. I glanced up the street and no one was coming so I just laid there to recover for a bit. When I did get up I figured I was an idiot so deserved to pedal the 12 miles home even as beat up as I was. Good to share this stuff might save someone from the same kind of incident.
 
This is a very common accident for cyclists. The other day i crossed some tracks at a less than smart angle, though I am skilled at un-weighting the front wheel intuitively when crossing.

If they are wet, it's super dangerous. It's much safer on my wider ebike tires than a road bike tire though.


Glad it wasn't too serious.
 
Sorry to hear about your crash. Glad to hear that you are mostly unscathed. It looks like the bike could have been much worse too.

The last time I wrote off a wheel (a nice 48 spoke 700c front I built myself) was due to train tracks. I was crossing the frontage road of IH35 in downtown where our pretend commuter train crosses. It was dark, I was trying not to get killed by heavy car traffic, and I goofed and stabbed the front wheel into the gap between pavement and rail. The bike stopped; somehow I vaulted over the bars and landed on my feet running without falling. I looked back and the bike was in the middle of the traffic lane standing upright, twanging from side to side from the jammed front wheel. Fortunately it did not get taken out by a car before I could go unstick it.

There is now a bike bridge leading to that freeway crossing from the other side of the tracks, thus no need to intersect them anymore. I still wish I could push a button and raise a set of retractable bollards to break the traffic sometimes.

Always jealous of your country, dude. Everything we do, you do better. I have yet to find an exception to that rule.
By the way, i am up for adoption. I will pay all fees. I do dishes very well, and am already adapted to high altitudes. Whaddya say? :mrgreen:

Our system is very screwy. If you have the government building the roads and supplying the health care, then there is an incentive to make the roads as safe as possible.

Instead you have government building the roads here but not having any real incentive to make them safe. You can throw $10,000-$100,000 into suing the city but your chances are low that anything will get done and your money will be returned. Is it really worth the money to fight an entity with special legal immunities? In most circumstances, the answer is no.

Now if healthcare was private and roads were private, this road would be a monster-sized liability for the company in charge of maintaining it. I would have never fallen because it would have already been fixed. Think about the supermarket that has to lay down a 'wet' sign next to a puddle of water in the store otherwise they can easily get sued for a million dollars. They are responsible for everything on their property, so they are hyper paranoid about presenting ANY risk to people on it.

Our mixed system is very broken, and i'd say i'm not a fan of it whatsoever.

Ah crap, now you got me talking about politics. :lol:
 
Thanks for the reminder to watch out for train tracks..

I can see it now - "For Sale: Da-Bomb ..only dropped once.." :wink: :lol:
 
Bah, other than the rear rack scrape, the bike is in great shape. No cracks, no bends, the thing is constructed entirely out of overly tough chromoly tubing, so it's not like an aluminum frame where you are wondering about it as you ride it afterwards.

It will find another home one way or another.
 
It's interesting this came up when it did.

Yesterday on the way home from work, I was waiting to cross Grand Ave, whcih is parallel with railroad tracks that often have trains on them at the times I am there, usually passing the intersection within 2-3 minutes, depending on how long they are. Grand goes from southeast to northwest, and is at 45 degrees to Northern (whcih goes east-west and is what I travel on right now), and another street goes over the top of the intersection via bridge, but has a feeder street that goes north-south and crosses at right angles to Northern ( and also 45 degrees to Grand).

I always cross the tracks at right angles to prevent the tire-stuck / crash problem.

But not all car drivers do...some of them are morons, and decide to go around the traffic control lights when red, whcih also say no right turns on red, by going onto the tracks themselves and then worming their way left into a lane. It's happened twice while I've been waiting to cross, once with a larger newer sedan, and once with a little bitty car (Yugo-sized, I'd guess).

I really wish I had had my camera with me, becuase that little car, with a donut on the rear left, got himself stuck on the tracks (not quite the way a bike can, but unable to get the tire over the rail while nearly parallel to them, after he'd run out of asphalt and was on the crossbeams and gravel part), while doing that stupid maneuver. He panicked and was spinning tires and throwing gravel, but couldn't get that tire up on the rails and over, just going further down the tracks, until finally he got smart and put it in reverse, until he was back on the asphalt at the intersection (but then he almost backed into another car waiting to turn--if that car hadn't themselves been watching, saw him coming, and backed up they would have been hit). This time he waited for the red light to clear.

Funny thing is that if he had just waited a few seconds, the light had changed to green while he was panicking to get off the tracks, and everyone else was already going, except me (because I waited off to the side to see what was going to happen, not being in any hurry to go home yet). By the time he figured out to back up onto the asphalt it had already changed to red again.



I've also seen three cars go across teh tracks while the train crossing lights are flashing but the train isn't there yet, then get stuck blocking part of Grand Ave with traffic flowing, other cars honking at them as they have to slow and go around them sticking out into their lane...but the car still isnt' clear of the tracks yet, and if a gap didnt' open up for them to go inot the traffic on Grand (which isnt' where they were trying to go, AFAICT) then they'd be hit by the train when it did finally get there. Again, if they were just patient, they could have crossed normally--one of the "trains" was just a couple of engines and no cars, so it only took about 30 seconds to cross and the traffic controls to let everyone thru again.



There arent' a lot of train tracks here in town, and the few places I've been two have them at nearly right angles to the road they cross, except for Grand--if you want to cross those at rigth angles you ahve to start in the right half of your lane, then go 45 degrees thru your lane while crossing, to end up in the left half of your lane and then go back to the right half or middle of your lane once across.

Interestingly no one has honked at me or tried to run me over while I did that, even when the light was green when I got there and no one slowed down from the 40-50MPH they're doing there, and I'm only at about 15-18MPH (because road conditions for about half a mile around that intersection are not very good). Hasn't mattered whether I was on the trike or on CrazyBike2 so far.



Anyway, just chiming in in my own wierd OT way. ;)

No doubt, steel is real. Why not sell it locally?

Show up at your local organic produce store or farmer's market on that thing, hang out ~20 feet away from it and enjoy a snack for an hour or so. People-watching is fun, especially when they start trying to explain your Longtail eBike to their friends. Strong chance that someone passing through wants/needs exactly what you got -> right there.
 
Amberwolf: wow. I'm amazed that a 4 wheeler could get stuck that way. I've never seen anyone try to pull that kinda stunt before.

Steve: interesting thought. The bike definitely gets lots of looks when it's out on the road, but it's a real oddball, made by a guy who has made maybe 10 frames total, ya know? I might try to hawk it on one of the gas bike forums soon.

If all else fails, i'll hack it up and get it rewelded to be shorter. Been thinking about doing that for months, just haven't felt like dumping $ into it.

So i have my MAC Trek back together and have been riding that since yesterday. You guys are right about being higher. The higher center of gravity is very tippy. I have that bike set up so that it's no longer a mountain bike as well - it's upright.
It swerves around naturally as i pedal it. Funny how a 50lb ebike seems flimsy in comparison.. :lol:

I kinda knicked a curb with the front tire and noticed the wheel wanting to move on it's own, kinda alarmed me and gave me some deja vu, hehe. I usually have my tires at 40psi, maybe it's time to let some air out of 'em and run 30psi or so, so that the tire can warp around irregularities in the road rather than try to bounce off them? also maybe some tires that are knobby on the sides could be helpful, rather than the smooth tires i normally run?

What can I say? People in Phoenix are often stupider than you could imagine until you see it. :roll:

I told a friend about it at lunch, and he said that he has seen even big-wheeled pickup trucks not be able to climb the rails sideways (parallel) like that, though usually they could go over them at a right angle.

Knobbies on the sides (like Kenda Kross/krossroads) might be ok on the back tire, but I find they cause more problems when turning if you have to lean much--somteimes the tire slips and prevents much of a lean, on regular asphalt, though it might help on dirt/gravel. They're what I have on DayGlo Avenger.

Lower pressure with lots of objects in teh road might work for osme tires, but others you could get pinch flats if the objects or holes are big enough. :(

I've had low tire pressure accidentally before and ended up with a damaged rim from a rock in the road (one of many golfball-sized pointy ones I could only avoid some of) that would've just caused a heckuva bump at normal pressure, but in this case pinch flatted the tube and dented the rim on one side so the brakes couldnt' let the wheel roll properly till they were readjusted inward toward the hub some (was catching on the outwardly-bent rim). That was back in my pedal-only days.
 
Here"s couple shots of tracks around here. Temp was +1C. They promised +5C for tomorrow. :) It won"t stay that high though yet.
Cobblestones here and there.

Like everyone else, I'm glad you're okay and will heal...

Like Ykick, I echo the MSF advise. Many 10's of thousands of miles on motorcycles and never down on tracks because of what I was taught. I've had skinny bicycle tires slip on tracks, but never down. Fatter tires do help, but overall diameter doesn't matter. Here in the Seattle area we also have draw-bridges with steel grated decks. Scary to go over on a bike or motorcycle, but doable IF one takes the lane at an angle. I make it my goal to memorize (yes, really) every track, man-hole cover and in-pavement junction box cover on my routes: anything made of steel that will be slick when wet, and I aim my bike/motorcycle to avoid them.

Two motorcycle dictums:

1. There are old bikers and bold bikers, but there are no old, bold bikers.
2. All bikers go down. You've either been down or are going down, it's simply a matter of time.

Ride safe.
