Designing a jump for a Slip ‘N SLide

/0 Comments/in , /by

Hey Lee,

I am thinking about building one of those giant slip n slides that uses a bungee cord to get people up to speed and sends them off a ramp at the end. I was thinking about doing a ramp somewhere between 45 and 60 degrees because I feel like going for more height than distance would be fun but I also don’t want to lose too much distance. Just wanted your opinion on that. Also I don’t have a clue how to do the curve of the ramp so any advice on that would help. At the moment I don’t know how fast we would be hitting the ramp because I can’t find a big enough bungee cord with a spring constant to do some calculations.

Thank you for your time,

Nolan

Thanks for the cornering skills

/0 Comments/in , /by
Hi Lee,
A quick ty for the class a couple of months back in Santa Cruz and for the access to the www.llbmtb.com content.  Applied the cornering skills to a high speed uphill turn with not much of a berm that comes at the bottom of a fast decent and I’m now able to carry a ton of speed through the turn. (:
Plus getting the handlebars near vertical feels cool too.  (pic attached)
I know we’re all getting pummeled by the lockdown so wanted to send a ty and wish you well!
Best,
Jere

Roller spacing for a kids’ pump track

/0 Comments/in , , /by

Hi Lee,

I bought the v2 of the pump track nation book. Gotta say super well written. I’m planning on building one in the back yard to keep my kids busy. They are 3 1/2 (good at strider) and almost 6 (he’s got a nice 20” bike and can ride mellow mtb trails)

My space in the yard is 35 feet wide and 32 feet deep but the SW corner has a shed so need to keep entrance clear so will likely do a trapezoid shape. That includes room for the back of berms.

My main question has to do with the 10 foot peak to peak number you mention as ideal for rollers. How tight can I make rollers. I assume since the kids are on small bikes they can handle tighter spacing. What’s a smaller spacing that would still be manageable for me. I’m advanced rider on a dj bike. I can pump my way around a pump track without pedaling but by no means an expert. Though I’d like to practice now that I have time. We are working from home for the next foreseeable future and we have the kids home too. All schools and daycares are shut down here for the next 2 months at least. Our local pump track will also be shut down for the foreseeable future.

Thanks
Bogdan

The higher you want to hop (relative to your ability), the more you need to unhinge and drive with your hips.

Nose bonks are an easy, efficient way to ride your mountain bike over obstacles.

They’re also a stepping stone to a proper bunny hop.

DIY deadlift device (video)

We should all be doing deadlifts, but many of us don’t have access to a gym (especially during the coronavirus crisis), nor do we have room for big weights at home. Here’s the DIY deadlift device I use when I’m home and on the road.

Pump tracks: Different radii in the interchanges?

/0 Comments/in , , /by

Hi Lee,

I’ve found your “Welcome to Pump Track Nation v2” e-book to be a great resource. The pictures and steps regarding interchanges listed on page 49-50 have been helpful but I am not fully confident with the exact design of my interchanges. My main question is, is it okay that the interchange berm has a different radius than the adjacent berm? I have drawn out a plan that I hope will work well. Is there anything that stands out that needs changing?

Thank you,
Dan

Roller height on the PumpTopia pump track?

/5 Comments/in , , /by

Hey Lee,

Just purchased the Pumptopia Track Plan and was reviewing some of the sheets while comparing some things in your ebook “Welcome to Pump Track Nation v2” and had a few questions.

In the ebook it mentions 12″ high rollers with 10′ from peak to peak for the rollers.  However, in the plans it shows 18″ for what looks like 10′ peak to peak on rollers?  Is there a reason for this?  Will it be faster or slower?

Doing the F6 training program with a bike handlebar

/0 Comments/in /by

Hi Lee, quick question.

In the F6 off-bike training book you have a caption to a photograph (on P14) that says…
“Rock the F6 anywhere with surgical tubing, adjustable
dumbbell and a handlebar (optional, to make squat
rows and lunge pushes more bike specific).”
Do you mean to use a handlebar on the end of the Resistance Band/Tube instead of the hand grips shown in the specific exercise photos ? and could this also be used on the ‘Hinge Pull’ or is that better with the twin hand grips?
Kind Regards
Peter

Hi Peter!

Thanks for reaching out.
Yes. You can hold the bar like in this photo. If your band has grips, you can hook the grips onto the middle of the bar and hold onto the end of the bar. This makes it more bike specific.

I hope this helps!
