You qualify if you hike, run, or bike to these locations and track your total mileage on the form. I logged 82 miles for this bottle. It’s a stainless steel, double-walled beauty in a nice blue—and not everyone has one. I thought it would be just a simple plastic bottle, but nope. Free gear just for biking around and checking out cool places! Now I'm stylin..

Just spooned these on yesterday and did a mix of road, gravel, and (dry) singletrack with these and they performed beautifully. Felt quick on the road, stable on gravel, and grippy on the trail. Haven't ridden in wet conditions yet, but first impressions are positive.

On my Tern BYB P8, I noticed that the color of lower right tube of the Metro Transit Rack was worn away. I then checked how this could have happened and found that this part of the Metro Transit Rack collided with the left spokes of the front wheel when rolling the folded bike. It seems that only the rack (which is made of alumin(i)um) was damaged and not the spokes, but I am not 100% sure. I am pretty sure that this is unrelated to the wider tires I am using because I did not change the frame or any part of the wheels.

In order to avoid the collision, I removed the Frame Lock Pin (parts list is linked here), added 3 washers, and fixed the pin again (using a longer screw). The problem is that now the bike is a bit (ca. 5 mm) wider (in most cases not a problem but it might cause the bike to no longer fit in certain narrow spaces). Also it seems to me that the two parts of the frame which are connected by the pin have a looser fit.

Unfortunately, a replacement Metro Transit Rack was as wide as the one that came with my bike (however the lower right tube was parallel to the upper tube - while on mine, there is a certain angle so it is less wide in its rear section), and my dealer didn’t have another BYB P8 to check and measure. And Tern support told the dealer that this problem is so far unknown to them and they think that the problem must be with the frame (which I do not believe, as the frame is perfectly fitting and stable when unfolded and does not show any type of wear, bending, or tolerances in the joints).

So if there are BYB P8 owners out there, could you please check if your Metro Transit Rack is also damaged on the right side, similar to mine, and maybe repeat my measurements? This would help understanding the scope of problem, and maybe help convincing Tern to produce a version of the rack with his ca. 5 mm less wide on the right side. I believe the rack needs to have a certain greater width on the right side to that a bag attached to that side of the rack would less likely collide with the derailllieur. But 5 mm less width should not be a problem.


This is where the lower right tube of the Metro Transit Rack has collided with the left spokes of the front wheel.

Here you can see that the 3 washers, with a total height of ca. 5 mm, cause the Frame Lock Pin to be positioned further out on the left side of the front fork.

This is the current distance between the lower right tube of the Metro Transit Rack and the left spokes of the front weel, after moving the Frame Lock Pin 5 mm farther outside of the front fork (using washers), for avoiding the collision.

I used this piece of cardboard to allow measuring the width of the lower right tube (from the frame) without having to unmount the rack from the bike again.

I found that the width of the right side of the rack is ca. 39 mm, causing the rack to touch the left spokes of the front wheel.

This shows the exact location of the frame where I measured the width.

This is my version of the Metro Transit Rack, shown after unmounting it. The lower right tube is at the top of the picture.

This was the replacement Metro Transit rack, with the same width as mine but the lower right tube (at the top of the picture) parallel to the other right tube. The maximum width was identical to mine, so it didn't solve the problem.

My small Zizzo pump works, but just barely, and I can only get up to 40 psi. I need something more effective, and I’d also prefer a tire pressure gauge so I don’t have to rely on adjusting by feel, which often leads to missed attempts and having to redo it.

Today in Ohio.....

So I’m starting university soon and am in the market for a folding bike, preferably a standard-sized mountain one.

For reference, my current bike is a non-folding Schwinn Bonafide 29 that I currently use on backroads, bumpy highways, and urban/suburban rail trails.

My budget is $1500, and I am currently eyeing the Montague Paratrooper.

edit: I'm gonna add a few more details that may be useful:
- target city: Pittsburgh, though I do plan to travel a bit with the bike
- height: around 5'7"
- quirk: Pittsburgh buses require that my bike be unfolded and stowed on the front bus bike racks instead of folded into the bus cabin...

Am I on the right track? Heard that Change-branded bikes are also a viable option, but not really sure on that either.

Any advice and/or recommendations welcome, thanks in advance :) ]]> Folding Bikes touhouengie https://www.bikeforums.net/folding-bikes/1320029-looking-folding-bike-trail-city-use.html https://www.bikeforums.net/folding-bikes/1319998-my-fleet-titanium-brompnots.html Tue, 14 Apr 2026 08:07:01 GMT Image: #1 - All black.

I think I have started building titanium Brompnots like 5-6 years ago. I have built one for my wife and another for my father, but due to health issues he returned the bike to me.

Recently I purchased two painted titanium main frames (black and green) so I ended up building 4 bikes from my parts bin.

My subjective feelings are as follows.

+ PROS:
Compact fold (smaller than brompton)
Multi-functional battery pack
Relatively light weight
Good to ride without battery

- CONS:
Could be lighter if the frame design can be optimized
Very low potential of further modifications.
Small battery

This is my third full-carbon folding bike. It has a weird name, "Pardus Intelligent RS".
To be honest, the previous two (CHEDECH 5 @2016 https://www.indiegogo.com/zh/project...ike-chedech--3 and UBIKE SPEEDSTER CARBON PRO @2019 https://www.pardusbicycle.com/intell...t-rs-sora.html) were actually unsatisfactory, both because of poor stiffness of frame.

But this one is much better. Thanks to the development of material technology (or thanks to the strong profile of the main frame), it rides as stiff as a Dahon Speed (my favorite folding bike).

Recently more can more carbon folding bikes appear. It seems integrating sophisticate metal folding mechanism into carbon material and meanwhile keeping the frame strong but light weighted is no longer a problem.
Maybe you could see full carbon Brompton and Birdy soon... who knows!

So it is of course much more affordable. One unexpected surprise is that the ride is actually stiffer.

Durability still needs to be further verified. It's been one year since I built it and so far no issues.

I just joined the Bikeforums site. Looks like it will be fun and full of useful info.
Thanks.
I inherited my mother's Kathia folding bike.
I think that she bought it in the 80's in Toronto, Ontario. Can anyone shed some light on it for me. Was it popular, easy to purchase, not too hard to find these days for parts, etc?
I want to re-furbish it starting with the flat inner tubes.
What size of tube should I look for, if I cannot patch it.
It could use a new chrome chain guard too. Any thoughts on where to find one of those?
Thanks everyone for your help. ]]> Folding Bikes howdydowdy https://www.bikeforums.net/folding-bikes/1319887-vintage-kathia-folding-bike.html
