Looks great! I like how you can make the battery placement or a non-hub motor mount where ever you shape the frame to accept them. I added this to the 9-page "wooden bikes" thread...

That's Awesome!

But How does it handle with so little head angle and such scarey amounts of negative trail?

[ohzee]

wow looks great nice use of some pretty oak.

[kriskros]

SM,than ks for the add on....the motor[1200watt cyclone] will go at the rear base of the seat post,and the therbattery['probably 44v,20amp lipo ]in the fronf ares DS... CORRECTION ..the head angle was changed to about 75 degrees,,, handling was sqirly at first, but the angle change corrected that problem

Nice bike...but am I seeing things right? Are your cranks at about 90 degrees to each other, rather than 180?

(I once installed a set that way by mistake, and didnt' realize it till I got on it hte first time. )

Maybe if I had made my newest bike out of wood, I would have had it finished by now.

i was having problems with the crank...the cyclone chainring has a recverse freewheel, and with trhe crank forward setup the pedals needed a toe strap to force a complete cycle... that picture was a little early ... cranks are now 180

AW, KK has something not right on his set-up.

Maybe you can analyze what is going on.

this problem was corrected quite easily....adding toe straps to keep the cranks in motion ...a suggestion from MOTORMEL:mrgreen:

[StudEbiker]

I think the toe straps are a "fix" but not the solution.

It is a nice work and sure has some originality.
Nevertheless, If you speed on this, you have more balls than I

Very unique! It'll definitely be an attention getter.

What the weight of the completed frame?
How long did it take you to build?

[rojitor]

Beautiful work! I wanna ride it.

weight of the bare frame,with steering tube and BB. about 15lbs... the complete bike was built over a period of about 6 months ,some health problems slowed me down.. in reasonable health it would only take about 2 days tomake the frame

[spinningmagnets]

The full suspension longtail I built had a similar "feet forward" posture, and I also used some BMX bars to allow me to sit upright instead of leaning forward. I find it to be very comfortable. I also found that on the few times I stood up to pedal, my knees brushed up against the handlebars. My bar clamp is mounted backwards right now to help place the BMX bars farther back.

For a while I've been wanting to rotate the bar-clamp back to the intended orientation and swap-in some beach cruiser bars with a lot of sweep-back. That would allow me to sit upright, and also plenty of knee room when standing on the pedals.

Really? That's very fast.

[kriskros]

the frame is really very simp0-le... just 4 pieces of plywood.[ actualy one 60x60 sheet of baltic birch cut in three,20x60..you only use two pieces]. easy to cut on a bandsaw[could also be cut with a sabre saw just as easily] and add three pieces of 2x4 ash..when i first started the bike i had the frame rough cut in about two hours.. the cutting and applying the 1/8 oak facing to all the p[ly edges took longer..the construction method could be applied to any style of bike you want... its simple,easy to make and very strong.. i had a 300pounder sit and ride this one

[liveforphysics]

That's pretty cool. I've been thinking about doing a wooden commuter bike myself. Something using CNC laser cut 3mm aircraft plywood with glued finger joints, perhaps no screws/nails. Make it so it's internal volume holds a few RC LiPo packs, and put a little hub motor on the back.

It's pretty low on the project list though, so it could be years before I got time.

What did you do for the steering tube on the frame?

[iamsofunny]

That's some nice work there
I once made a wooden ski fork for my bike and went snow biking

[kriskros]

LFP...the steerinf post waqs made bywelding two 2"x12"x1/8strips of steel strips to a steel tube and bending them around ... ... a2"x4" x5" block of ash was grooved on one edge to fit the yube...the stee strips were inset into the ash and epoxied in place...ther block is bolted and epoxied in between the two baltic birch sides.. it wont be going anyplace soont.. ... actualy i "should have made the post about 4" longer to come above the frame... there is a picture of this block on the original post "wood bike frame build". ..aircraft play would be very light and strong,but might be too flexible for a bike frame,especialy wth the power you like to run
