    Hello,

    It's a year, since I began my second velocar project , so I want to show the results so far.
    The Roadster is not ready yet, but I hope to complete it in early spring.
    Recently I'm 50% through the construction of the front hood.

    Specs:

    Quadricycle
    Capacity: 2 adults (sociable) + 2 small childs
    Length: 300cm+/10ft
    Width: 113cm/3ft 8inch
    Height: Body 79cm/ 31inch, Soft top 115cm/3ft 9inch
    Frame weight: 15kg
    Chassis weight (with suspension/axle parts, complete wheels (2x NuVinci) and steering, transmission still missing): 37kg
    Overall weight: 65-70kg (I hope so)
    A hub motor instead of Nuvinci and Lifepo4 battery+controller may add 6-7kg

    Frame and body parts are build from 4mm Okoume/Gaboon plywood with spruce girders.

    The chassis is standing on it's own wheels !!!

    A first test with cheap poplar plywood, to control the right shape. Thanks Steffen

    Knee clearance is a bit tight, I have to shift the dashboard 5cm forward

    Additional cutouts for the knees of the riders.
    I'm dreaming about a very old brass clock in the middle of the dashboard

    This is what I've dreamed of doing since I was a kid. I'll be following along on this. Thanks for sharing!

    Thanks for your comments.
    My favoured paint scheme is green, black and wood.
    Most edges of the body will be painted dark green after filling all screw holes.
    I want to paint black lines on the borders between green and clear finished wood.

    Hello plycar,

    Great to see you back. What a wonderfully thought out build once again. Thank you for sharing it.

    Steve.

    That's really cool. Your steering setup looks well designed and very adjustable. I would like to build something similar, but with only three wheels to maintain street legality.

    Luckily, here in Germany the number of wheels of an E-assisted pedal vehicle doesn't matter at all.
    A guy from Berlin has built an eight-wheeled pedal truck with E-motor and can drive it legally in traffic.
    http://www.nicojungel.net/space.html
    In the UK, they changed the law in mid 2015 and E-quadracycles seeming to be legal now.
    I don't have understood completely the new UK-regulation, due to the bureaucratic English language, I even have problems to read bureaucratic German :D
    In case of the US, it may be almost impossible to have booth four wheels and E-assist in a legal pedal vehicle.
    But as I learned, the regulations differ from state to state, right?

    "But as I learned, the regulations differ from state to state, right? "
    There is a National law in the USA legalizing 4 wheel, electric vehicles regulated to 20mph or less. If you are capable of better than 20 mph, better to have three wheels to be considered a motorcycle. Otherwise, you will need 5 mph bumpers, air bags, and lots of additional safety equipment.

    A short building update:
    [​IMG]
    [​IMG]
    Door frames glued and doors finally cut out.
    With outside hinges they will be able to swing 180°, as shown

    [​IMG]
    [​IMG]
    Top panel temporarily attached and edges partly trimmed.

    [​IMG]
    The hole in the front will be closed by the head lights and a "hood", next weeks main issue.
    Due to my trial&error building method this will take some time.

    Thanks, SB and yep, looks like :)
    But, as I know Banshee, she'd rather run beside the velocar, than sit in it.
    Maybe after a few miles ;)

    Tomorrow I will do further work on the velocar.
    I was not able since last Thursday, because of a severe cold.
    A lot of functional stuff is still to do.
    Steering column,handlebar, brakes and transmission.
    The design is nice so far (IMHO), but worthless without all that.
    I hope in early spring I can do my first test rides.

    Kai

    Those 'gull wing' doors are just too cool. Keep the progress photos coming. They're much appreciated and enjoyed.
