Hi guys. I just finished making my first homemade bent.

Had to teach myseld to weld and everything. Here are the specs and some pics.

Weight: 37 pounds
BB Height: 31 Inches.
Wheelbase: 49 inches
Trail: approx 2 inches
Seat height: 21 inches w/ pad= 22.5
From boom = 12 inches
Seat back to bottom bracket = 32 inches
Rear boom 29 inches
Chainstay: 15 inches

Handlebars are made from cut-off riser bars with MTB bar ends clamped on. The mast is a 15" seatpost. Seat is made from a skateboard and door hinges. Padding is a yoga mat. front idler is 2 skateboard wheels. Cranks are Suginos 165mm. Everything else (except the tires) came from donor bikes. Frame is 1.5 steel tubing and the chainstays are an old steel fork shoved up the back. Build from the great plans at www.atomiczombie.com

Congrats on your build. I like your adjustable seat and the whole setup looks good...i am curious, Is the seat comfortable, it looks like it should be but sometimes looks can be decieving... I used a plastic seat on mine and on a longer ride it gets hard. guess I need to use some padding. Mine is also small front wheel so the setup is a little different.
again Contrats on a great build...if this is your first one you have a great future in homebuilding.

Looks like a GREAT homebuilt. I'm thinking you need a long-cage derailleur though; and even with that, your chain may be too long.

We will need a ride report to go with those pics.

Thanks for the kind words.

In the pic I am on the small chainring and one of the smaller sprockets...hence the slack. To set the chain length I removed the derailuer put the chain on the largest chainwheel and largest sprocket and overlapped by one link. I'll have to look into the long cage derailuer, as I do get a lot of chain slap and the occasional hop off the front idler.
