So I dialed it up to 180 rpm..........

First time 18 mph with the dog trike. That's 180 rpm (single speed). I had more in me, but it was time to slow down for the upcoming conditions. 200 rpm is coming next time. It's much easier to reach high rpm with something heavy because it does not bounce around much from your leg movements. Only place I do this is abandoned pavement with nothing around.
18 or 20 mph is too dangerous with any thing/one around with an upright trike and a dog in it. However it would be fun to drop a couple of riders while on a 39 year old trike with a 35 lb. dog in it.

Where's a terminally out of shape poseur with almost flat tires when I need one?
Looks Like Bailey and I have to take a trip to Prospect Park and dial it up to 250 rpm.
Road bike for wussy.

180 rpm? Do you have a cadence equipped computer to verify this?
seems uber fast

Yep. And I timed it at a lower rpm to see if it was reading right. It seems right. It feels insane uber fast.

I don't think I can do 180 on my light weight racing bike everything starts bouncing around. I've done 150 on other bikes.

The heavy bike stablilizes the seat and the pedals making the pulses more even. At least that's what it feels like. Also the cranks are short on the trike to prevent pedal strike, it only has 24" wheels. Maybe the short cranks help. It's hard to tell.

Not that it would be particularly feasible to get dog and trike to Brooklyn, but if you ever do, 2many, you must get pictures.

That would have been fun to see.

I've hit 185 before. You have to be accelerating with resistance or you bounce a lot. As soon as you start to slow down and lose resistance it gets tough to maintain smoothness. On my normal geared bike I start to get a little bouncy around 120 but then with concentration I smooth out again around 140.

That's it! You're right, when I am accelerating slightly it's much easier, did not think of that until you mentioned it. Having the weight and the air resistance of the trike must give me more to push against but it's geared so low I can reach high rpm.

So I dialed it up to 400 watts and..........

wow...I wonder how fast can a person pedal?
Guiness book anyone?

Who worries about pedal strike on a trike?

You are one insane mofo, the highest I've hit on my track bike was like 160 and I was all over the place...

An adult upright trike with 24" wheels has the BB close to the ground. If you have one wheel in a low spot you can still hit a pedal. Like when going off of pavement to the grass, if there is a depression in the ground for a side wheel. Or going over some bumps, or a dip in the pavement like a drain with the pavement slanted towards the drain. Only an upright trike like in my sig photos. My guess is they build them low to help the stability.
However, you can scrape a seat on a recumbent trike.

Something about the trike makes high rpm easier. With the dog, and some water, and its steel wheels, it's about 100 lbs. I think the weight and the wheels working as a flywheel smooth out the pulses made by each stroke, and make everything hold still more.
Also the trike on a flat surface has very little side to side tipping movement. The three wheels does act a little like a tripod. I can also go a mile with no bumps or intersections on that flat bike path. Maybe that path being flat as a pool table and perfectly smooth helps ??? I'm going for 200rpm next time out if I feel good.
Around 1994-95 I did 220 rpm once, on my Dave Scott Ironman Centurion. Now old guy feels old again.
I may not get over 160 on my track bike either. It does not have cadence, I could not bring myself to add a wire going down the down tube. It looked out of place to me. How do you have yours set up?

I don't need a cadence sensor on my track bike, it's a track bike.
I can tell by the speed.

What is wrong with me? I should have thought of that.

48x17 @ 160 rpm = 400 watts, roughly 36 mph, uphill.



I mean downhill...

Glad you brought it up. I'll be using it when I go for 161 rpm on my track bike.
