RAIL BIKE - Version 5 - Added adjustability & removed the outrigger -- Building my own railbike 

Skateboard wheels, and tapered to give it more width, and tapered to help keep it centered on the rail, and somekind of suspension, spare parts, and tools in a low center of gravity positioned compartment on the out rigging arm to prevent hopping and maybe a helmet because the tracks and everything that your riding on is unforgiving in every way!!. Thankyou so much for this video!!!!

The lead project manager is finally revealed. "the more parts, the more problems", "keep it simple (stupid), K.I.S.S.!" The lady has style.

que dolubo querido🐤, esas ruedas tienen una corredera , la ajustas con una llave fija y listo loco 🙆Saludos de Argentina

I enjoyed the video especially guest appearance from your mom. Favorite part was her uncontrolled laughter in the background!

Great design,amazing

that lady has some nice 964's!!!

@Suluk46 >>> 👍👍

I bet the smoothness of riding those rails is very enjoyable. Just quieter and way less bumpy, Sounds like a good time. I want to ride one now. Thanks for sharing. An electric motor for my near 60 year old body sounds good too.

Nice but you definitely need lock washers in there and maybe some rubber grommets to disperse some of that energy.

What about springs? For the guide wheels. That way they could automatically adjust to the different rail conditions one experiences while riding. Finding the correct springs for the job would probably be the toughest part. If they are too strong, they won't adapt but if they're too weak, instead of adapting they'll be bouncing out of place.

Thanks for including the part on trying to ride without the outrigger. As I said, getting started and stopping is going to be the hard part. It's not until you are going fast enough that the gyroscopic effect of the wheels will help you stay up. As you show in the video, the control dynamics are different than riding the bicycle without the guide, and training your brain to do it is not trivial. Given your guide, why don't you just try riding with the guide down on the street? That way you have much more leeway to learn how it works without immediately failing. Your experience so far reminds me of trying to learn to sailboard. The control response needs to be so fast that it needs to get into muscle memory. But since everyone else out there posting videos of rail bikes is also using an outrigger that definitely seems like a reasonable option. One interesting piece in your video was the camera view from the outrigger showing the swinging of your bag of rocks. That is important for the dynamics. It shows you the spring action of the bar and at least one of the frequency modes. Much of that is the spring constant of the bar, but it might also give you some insight into the driving frequency(ies). This could be helpful in designing your outrigger. I would like to see your measurements of the spring constant of the outrigger. In the next iteration what means are you thinking of to add dampening, especially adjustable dampening, as well as adjustable mass, to the outrigger? Right now you can add rocks and move it in and out, which might be enough mass adjustment, but you need some dampening I would guess.

OMG! Your mom's laughing was just cracking me up, she is a riot! I think you should include her in more videos. lol Listen to your mom's advice, if she could teach elementary she can do anything! haha! Too cute that she worries about you, that's a mom for ya! Thanks for sharing! :) :)

Look on the bright side, more parts means you have spares! The axiom states, "Quality over quantity, but quantity has a quality all it's own." put a luggage rack on the back, and you can brace the outrigger diagonally. Still think you should try trailing the front guide, rather than pushing it....

I think the problem w/out the outrigger is getting started. Like riding skinnies, you will have a hard time starting form a stop on the skinny. But if you have momentum going into the skinny it's really not too hard. Wonder if the guide had some lateral flex?

I would try horizontal wheels on the sides. Yes, it may not work on crossings, but just heading down the rails would be more stable....my 2 cents.

i've been following along... have a railbike idea myself... my one thought, would be to combine the outrigger with the front wheel guide into a single unit...? also, due to the potential for stress on that front guide part, perhaps pulling that little fastener through the slot of the aluminum guide arm, add a washer? in my version (steel, because, weight is better than lightness IMO), i think i'm removing the front wheel completely, and going into a fork mount, while, having a (yakima style?) fork to hold the front wheel onto the outrigger (adds ballast)... i have a couple ideas about adding a second wheel fork, that allows me to 'tow' the set up, like a trailer, when not on the rails, even incorporating a 'bike packing' element within the added outrigger brace, so the entire package is compact, practical, and, can add ballast to outrigger while on rails... hmmm.... if i were to do a 'cross-country' version, for sure i'd consider going more lightweight with aluminum, as long as the strength wasn't compromised.... great project! keep it going!!

Front guide should be vertical flat steel guide wheels and one center rubber for comfort. You should be able to pedal with no handlebars. The wheels will steer you. Weigh the bag and fill tube on outer end with lead to match.

Version 6 should be a tandem bike for you and Mom.

you tried the impossible 😂 I have my front guide built, now I'm working on my outrigger.

So fresh! First like, first comment! I wonder if you put the front guide behind the wheel if you could get through the tight spots.

Any thoughts on adding a bar from the middle of the outrigger towards the bottom or base of the outrigger wheels? Would that add any stability? I feel like the outrigger isn't stable and wont be strong enough for a longer distance and you may snap that bolt again.

I've wanted to do this bike on the rails thing for a long time. Then I got the electric bike, and I wanted to do it even more. Now the electric motorcycle, so I really want to find a parts source. I have an entire tote of these wheels in bright neon colors so that's huge. Remove the outrigger? You're taking the fewer parts thing to the extreme. You would have to have a large gyroscope mounted under the frame. So anyway thanks for the incentive. Oh and there's no film in your GoPro, so you're not "filming." Think of another word, and lose the film, cuz we don't use cellulose anymore.

I think your mom is the better designer of the two of you

Very cool.... However what this guy is doing is considered trespassing by the company that owns the track....
