So this was my Dad’s pride and joy. He worked on it and took great care of it. I know it is a Catrike but that is just about it. We are getting ready to pass on some of his items and I was just hoping someone into these bikes might be able to give me a bit more info about it. He bought the bike for more than a thousand for it. What is a solid asking price to sell it? Any help is greatly appreciated. I am not selling on Reddit. Just looking for information.
Hi everyone — this is a long shot, but I’m hoping someone here might be able to help.
Does anyone happen to have an old Schwinn Airdyne A3 or A4 exercise bike that’s no longer in use? I’m specifically looking for the small battery holder/compartment that attaches to the back of the display.
Ours went missing during a move, and without it the display won’t function at all. I’ve attached a photo for reference so you can see the exact piece I mean.
I’d be happy to buy it from you if you’re willing to part with it. Thanks so much in advance — I really appreciate any leads or help!
I have a new Ice Sprint X Tour with a Rohloff hub. Really would like to monitor only speed, distance, perhaps cadence, and not to be wedded to smartphone for every ride and training session. Looking at the CYCPLUS GPS Wireless Bike Computer but the hangup is installing a speed sensor on a trike that will sometimes be on a trainer. Any tried and successful solutions?

I've (47M) been an avid cyclings for a few decades now and really enjoyed riding hard with groups and racing But over the last few years, and even more so recently, I’ve developed severe foraminal stenosis on my left side which leaves me with very numb hands after only about 15’ of mountain biking. I can road ride as long as I keep my head down as much as possible so that my neck is straight. This has made rides longer than 1:30 to be more of a chore and not hugely enjoyable since I’m constantly having to concentrate on how I’m feeling and signs of numbness and discomfort rather than just enjoying the ride.
With this, I think that I’m going to have to change to a recumbent much sooner than I’d like to if I want to continue riding long (1:00+). The thought of this is causing me actual grief and depression. I fear that my riding hard days will end with the change and that I won’t be able to participate in fast group rides anymore.
Does there happen to be any recumbent riders in this group who have had to, for health reasons, made this change? If so, how did you deal with the change mentally?
● How much balance and coordination do they require to stay on?
● Do they flip/tip easily?
● Do they come with seat belts or would those be too dangerous?
● Are they safe for people with ~~~dyslexia~~~ dyspraxia or other issues impacting coordination
● Are they good for Bikejorning?
● Are they good for canine cycling?
● Can a pet basket or a screened wagon be attached?
My Flevotrike axle is bent and needs to be replaced. The Trike has a front wheel drive with an internal gear hub as well as a 5 gear cassette on the outside (Free wheel). The internal gear mechanism is controlled by a little chain mechanism that attaches to a little horizontal metal bar (around the 8cm mark on the axle photo)
The issue is the axle though..its bent enough that I dont want to ride 2000km on it as the wheel wobbles but I cannot find any source identifying what the axle model number let alone links to a shop that sells it. The internal hub mechanism and the cassette are a strange combination to have..I usually see axles that support one or the other, not both.
Does anyone know the axle type?
I have a recumbent trike already but I just stumbled across this one in a Pawn Shop. The front gears aren't shifting and the tires are flat but it looks to be in good condition otherwise. Should I snag this?
2025-26 Catrike Bosch eCat ActiveLine Plus Motor BES3 Smart System Upgrade Kit w/SuperNova Lights and Rohloff e-14 Smart System - 20 Inch Wheel Upgrade for Catrike? These are listed as options for front and rear gearing, respectively. Thanks!
Inherited this bike, what is it worth?
Inherited this bike, what is it worth? I believe it’s an HP Velotechnik Scorpion FS, I’ve included pictures of the customizations made to it.
Wanted to ride with my partner on one of the many NYC greenways or parks with laps, was wondering if any company rents the ice vortex + or Velotechnik scorpion full suspension.
Would really love to try the ICE Adventure - PERS Trike - Chainless Pedaling System
pedal by wire or any of the cool tech introduced in SPEZI 2026!
Clean, maintenance-free, chainless e-assist cycling sounds awesome!
Thanks!
Hello all - I recently got my tire replaced and didn’t realize the valve stem was different until I got back. The threading has been difficult for my floor pump to grab, and now my floor pump is having trouble with the other two tires as well (normal valve stems on each). It no longer works at all on the threaded stem, so I can’t ride my beloved trike until I get this situation in hand.
I worry that grabbing threaded metal rather than rubber is ruining the plastic connector device on my pump.
Do any of y’all have this kind of nothing-but-threads valve stem? If so, what are its advantages? Regardless, how do you fill your tires?
My dealer is 90 minutes away so this would be a big help. I feel like there’s something I am missing…?
Hi everyone,
I'm new to the sub, but I still wanted to share my upgrade.
I started on a blue Challenge Twister, secondhand, 21 gears, magura breaks, understeer, back in 2023 when I was 26. It served me well but, unfortunately, it's on its last set of tires. Meaning, the upcoming maintenance is a bit too pricey for me. The rest rim is running out of material to break on, the brakes need replacing, stuff like that. It's been a fun commute the last couple of years though.
I've upgraded to a red Sinner Spirit with 54 gears (way more then necessary), understeer, kickstand and v-brakes that's hardly been used as far as I can judge. The price? €400. I've transplanted some parts i.e. the flag, lights, front wheel with a dynamo hub, oilled the chain and she's ready to go..
The picture of the Twister is after stepping and Spirit before adding the parts.
My husband took my daughter for a ride in her new hase trix and now it looks like this and I have no idea why or how!? (Please be kind. The bike shop we got this from didn't give us much advice on how to fix or repair it. They just handed it over. We have had it for 2 months. It was making clicking sounds when she was riding it earlier today. It sounded like she was between gears but it didnt change when she shifted.)
Pulley on my Sun Seeker over under chain idler ate the shaft (pic 3) in less than 100 miles. So, I got a ¼" x 5" SS bolt with ¼" i.d. to ⅜" o.d. bronze spacers as a bearing surface. The pulleys have an inner bore of 10 mm; they are a little loose as ⅜" = 9.525 mm, but I think that will help them from digging in as they float laterally. Also, lateral travel is up from about 1.6" to 2". Reused the "keeps the chain from flying off on bumps" device. $9 all in.
P. S. I can't believe there's no bearings in these pulleys! I greased them too little, too late. Poor design. I know I can buy aluminum ones with sealed bearings, but $50 EACH!?!
So I picked up my first recumbent (used) yesterday, and cycled a small 10 km on it. And am enjoying it up to now. It's a Prozenergy Race (as minimally described here: Prozenergy Ligfietsen Race — Ligfiets.net). See picture below.
I posted before on the carrier/rack, but I think for now, I'll be fine. Just strap a small bag on the back with clothes to change into at the office, and keep a backpack on my lap with work stuff and food.
But I do have other questions, and as I have no one to ask directly, I'll ask here.
- I'm not sure if I'm sitting on it correctly, or if I need to adjust the boom some more. I noticed my bum starts to slide off to the front after a while. Could also be the awkward headrest (improvised by a previous owner) actually pushing against my helmet instead of really giving it a good rest. What rules of thumb are for the correct sitting position? My legs are just slightly bent when pedaling - so I think the boom is roughly on the right distance?
- What small accessories (or accessories that can easily be carried over to another bike) are worth getting? This is my "trial" bike to see if it's worth it to save up for a "real/better" bike - so I don't want to upgrade this too much (unless that's actually really worth it?). I'm used to my phone as GPS on a steering wheel, but that won't fit here. Also, the frame is angled all over, so most off-the-shelf bike-phone-holders won't work here. Or are there models I have yet to discover? Same goes for a bell (the bright blue thing is a bell, but besides it being broken, it's very awkwardly placed to properly use).
- Is there/are there good (technical) resources on the upkeep of a recumbent bike? Most information I can find is spread out across discussion platforms, and less like a single point of info.
I only had three bad encounters in all my years on two wheels, all of which were lessened by my height on the road bicycles. One angry dog that missed my leg because I was so high. One drunk driver who got a pedal scraped on his door. And one ahole who threw acid at me but missed because I saw him in the side mirror getting ready. All of these happened in NJ and thankfully I no longer live there.
