Just Bought My First Recumbent

I bought a used Mikado (Quetzal) LWB recumbent. I saw it for sale on Kijiji and the guy wanted $125, so I went to get it.

I looked at it and since I had never been on a recumbent, I didn't get on since I figured I would do it in the safety of my driveway.
I got it home and it is too small. I have short legs, 28" inseam, and with the pedals adjusted all the way forward, I still have a difficult
time getting my legs on the pedals in the back position.

The wheelbase is 55" and the bottom bracket is 20" from the front of the seat. I have no idea on the sizing of these types of bikes, so
I need a little help.

I only paid $125 so if I need to do a little work on it, I do not mind.

Thanks,
Ian

Here it is...

Is it that the pedals are too far forward, or not forward enough?

Quetzal did build a kid's recumbent, if the BB is all the way forward and it's still too small, it's too small.

Nifty bike, never seen one of those before

The pedals are not far enough forward. I am thinking that because I did get it so inexpensive and another is going to cost me at
least another $250 (from the prices I have seen), I might have this one strengthened and stretched by about 4 inches.

Maybe you can clean it up and sell it for more than you paid for it.

What size are the crankarms? Would longer ones help?

Yes, if that is 20 inches from the front of the seat to the center of the bottom bracket, figure the seat is 10? inches long, the cranks are 7, that would give you a X seam (tailbone to feet) of 37 inches, so it might fit someone with a maximum of a 31? inch inseam. Not too terribly short unless you are a goon like me. If it is too short, I would not modify it, I'd clean it up and sell it to fund another bike that fits, modifying may make it unsafe, ugly and unsellable!

The crank arms are 170s, shorter arms would help, but not the 5mm 165 arms (do they make 165 arms?) would give me.

I have an inseam of 28 inches, my X-seam I haven't measured yet.

The pedals are too close to me. With the pedals at their farthest adjustment, my outbound foot is about an inch too close, not that terrible, but
my inbound foot is in my chest. Maybe it's something I have to get used to since this is my first time trying a recumbent.

As for selling it, I don't know the market here in Montreal. I;m in the middle of cleaning/jubing it and replacing the cables and housings. When I am
done I will post it and see how my luck is and see about getting a longer one, or one with more adjustment.

Does anyone know what the wheelbase on these types of bikes are? Maybe the length between the front of the seat and the middle of the BB?
This would give me a good idea of the sizing of these beasts. I have looked around the net, but couldn't find anything yet.

Thanks,
Ian

I bought my mother a delta trike by the same company, she has the same problem with the setup. The one solution I found but have to clear with her first is to lay the seat back about 15-20 degrees and that will take putting your knees out of your chest. For a recumbent it has a very high angle for the seat back. Everything else is just right for her so changing the length of the crank arms or changing the distance to the peddles is not necessary.

On the one I just got, the seat moves back and forth to accommodate a wide range of people sizes, the frames are all the same. Not sure about other makers.MK

OP,, Sell the bike, Cutting, welding, sleeving the frame is a bad Idea. most of these bike have a relatively thin walled frame of some unknown metallurgy.

Welding can weaken the metal and can force stresses past break points elsewhere on the frame. Most have some built in flex.

You cut or weld and you remove this variable,,,,

SNAP,
Crash,
Ambulance,
Hospital,

$125 bike cost you $20,000

Just sayin.

Moveable bottom bracket

From just looking at your pictures, it appears that you can loosen the Allen bolts holding the bottom bracket to the frame and move the BB back and forth to adjust for riders of different heights (distance called X-seam by recumbent riders). I can't imagine any bike maker would make so many different frame sizes for different riders. On most long wheelbase recumbents you can either move the seat or the BB. Don't forget if you move the BB closer to the seat, you will have to take out twice as many inches of chain to accommodate the change or the chain will droop way down as you shorten the distance.

Good luck. See if the BB moves!

I never liked that model. It was made under several brand names: first CCM, then Peugeot, then Mikado; each one a failure. They never sold more than a handful outside of Canada. My first inclination would be to sell it and try to get back the money you paid.

If the bike is too small for you, and you're stuck with it, then your options are limited. You can get a crankset with *longer* crank arms, which will move the pedals away from you at the far end of the pedal stroke, or you can find a way to move the bottom bracket further away. Is the frame extendable? By that I mean, is there a set of pinch bolts somewhere along the main tube, so you could adjust the frame there? Another possibility is if you could recline the seat more, which would have the same effect as moving the BB forward.

This is the first thing I did. It was a bit better but still too short. I did manage to get the BB about 2 inches farther forward by doing a little modification
and it seems almost perfect now.

This model does not have the extendable frame. This manufacturer does make frames like this, but I think mine is an older model, so just the BB moves.
Moving the seat isn't possible without modifications as the seat mounting points are fixed.

I'm changing all the derailleur and brake cables now, along with replacing the Altus cantis for STX-RC cantis (They are stronger and I had them lying around).
I hate grip shifters, always have. I have a set of Alivio rapidfire shifters that I would like to use, and I am trying to see how I can mount a horizontal bar from
the handlebars to mount them. No idea if they will work though.

The seat has a metal frame and is covered my a mesh with inflatable cushions inside, nice touch.

This is what I want to build. I have been looking around the net for a while and this seems like the best one to build.
My neighbour has a small mig welder that I can use, so it's just a matter of getting the materials together and figuring out how to put is all together.

Longer crank arms won't help because although they'll be farther away at the bottom of the stroke, they'll be closer at the top of the stroke. It's too small ,sell it.

It's not too small. I'm just an idiot. This is my first recumbent and I am fat (the reason I bought it, to ride and lose weight) and my knees aren't the bee's knees.

I got on the bike and thought my feet didn't fit on the pedals on the back stroke so I thought it was too small. The whole problem are my knees don't bend as they should.
I will have to get used to it, that's all.

Thanks everyone for all the input,
Ian

OP, You prolly know this but just in case,,,

Sit the bike, and put your Heel right onto a pedals axsis/center, when the pedal is as far from your hip as possible your knee should lock straight...
Lock you adjustments down. Now put the ball of your foot on the pedal at the farthest extension, should net you a perfect knee bend angle..

Note: On Bents we don't have the option of powering down on the pedals with body weight so,, a slightly shorter set up may work for you,,,,,

Thanks for the help. I found the problem, it's not the crank length or the distance between the seat and the crank, it's the seat angle.
I did a little surgery and mounted the seat at more of an angle and found I could now pedal without any problems.

This little change allows the seat to recline more.

Yeah, that looks like it'll be a bit more comfortable, instead of having your knees in your chest. And it'll effectively increase the seat-to-pedal distance.
