Hi guys,

I have been looking at the HR and think that it looks way cool! My question is if changing it to a 26/20 wheel combination would throw off the balance and handling. I have tried a few tadpole style trikes where the BB was higher than the seat and I guess my circulation isn't good enough to be comfortable very long in that position. That's why I have always stayed with the LWB bikes.

Would going to a 20" front fork and tire drop the front enough that my feet would at least be level with the seat?

Also do you have any ideas for mounting lights on the front and some type of low center of gravity rack setup to carry a change of clothes, etc. for commuting?

Somewhere around the rear triangle would seem most logical. Maybe add a triangular rack from the top of the seat brace shooting backwards and then coming back in to meet the seat stays? Some ideas?

Not really "low" C.O.G. though. I see lots of guys on commercial bents with smaller backpacks, etc draped over the back of their seat

How about this:

Thanks Greenhorn,

I couldn't see your pictures though. I don't know if it is my computer or if they didn't load right.

In reviewing my set of Brad's plans it does indicate that you can use a 20" front. The only change required is the angle relationship between the head tube and the boom. I say go for it. I am going to stick with 26's on both ends because of my donor bike availablity and I just think the large front wheel dia my ride softer though this is just my opinion, not fact.
