Knee angle on ICE Adventure RS recumbent trike

[PAB855]

At what angle should my knee be on an Adventure RS recumbent trike which is normally used by my wife. She is 5ft 6in and I am 6ft and 0.5 inches ! Perhaps a suggestion of how far forward I need to adjust the boom would be a simpler solution as it was set up for her by a knowledgeable person after purchase when new.

I m not concerned too much about how well the gearing will work for now as this exercise is more of an experiment than anything else and it does have a retrofitted e assist pedal sensor with a throttle .

Cheers

I start off with “heel on the pedal” when straight, and adjust from there for comfort.
The exact distance will vary slightly as you move up and down the seat.

That sounds simple, much the same as a bicycle!

Thanks Bob

If there's 6" in height between you and your wife, unless you have a very wide range chain tensioner, you will need to add chain links to accommodate the extra boom length, which makes it awkward for two people of different heights to quickly adjust the length for their use. I know some bikes/trikes do come with such a thing, or can have one as an extra fitting. Perhaps the ICE Adventure RS already has one.

Being 5'5" myself, I've had to cut the boom on my last bike, a HPV Grasshopper, to get it to fit (as per manual). If that's the case with your wife, you need to make sure there's enough boom left inside the frame when extending it for a taller person.

Just some things to consider.
