    Disc brake size

    160mm discs can work on the 7" and 5.5" axle support tubes called for in the rear frame of the Deltarunner plans. What calipers you choose and their placement are YMMV territory. When the pillow block bearings are mounted to the ends of the axle support tubes, the center of the axle will be...

    What AZ'er wouldn't lke to have gone to this ?

    From the picture it looks like it has pillow block bearings on either side of the frame that holds the silver angled round bar in place with the right side of the bar connected to where the left crank arm would normally go. The straight piece of the round bar in the center of the picture is the...

    Rhoades Car revamp, got questions

    Skull Bucket Garage had a thread about the Rhoades car he picked up and was restoring. He also posted some pictures in the gallery. I remember posting some Rhoades related links in that thread because Skull Bucket had drum brakes and was interested in converting to disc brakes. Maybe you...

    Independent rear suspension on delta trike?

    The 17 Sep 2012 AZ newsletter had the following picture of a delta trike with "full suspension". It looks to me like he used two rear suspension triangles, one for each rear wheel. I was wondering if this arrangement would have any benefits over the AZ delta trikes like the Timberwolf or...

    Delta trike w/ e-assist

    In some places, yes. 24" front and back Agreed. My mindset was to design in the mounting for all the shafts and motor from the beginning to avoid reworking the frame. I can save weight by removing shafts and the associated bearings and, if necessary, moving FWs between shafts. My gearing...

    Delta trike w/ e-assist

    Apologies in advance for a long post, I've been mulling over the design of a delta trike for a while now. Something for casual riding, trips to the grocery store, and maybe someday commuting to/from work. Mostly on paved roads but the occasional gravel road/driveway. The two main factors...

    StreetFighter QuadCycle electric motor

    Dan, In case you weren't aware, on the AZ deltas with 26" rear wheels the plans call for 3.5" between the hub flanges for additional lateral stability. If you're concerned about braking you could use 180mm or 203mm brake rotors vice the normal 160mm, but you may need to extend the rear frame to...

    Another take on freewheel differential

    Stormbird, Can you tell me what your criteria is for least / most risk? Are you referring to difficulty to implement or some other measure? One of the best solutions I've come across for large uninterrupted cargo area is what Lightfoot did with the frames of their line of delta cargo trikes...

    Is it acceptable to mount a pair of sprockets on a disc brake mount ?

    Stormbird, I've seen multiple instances of using an IGH paired with a differential on Greenspeed Anura on the Utah Trikes site. Top photo is with Alfine hub, bottom is Nuvinci Utah Trikes also converts tadpoles into quads. Here's a picture of a Catrike conversion where they used a...

    Another take on freewheel differential

    Stormbird, you bring up a good point. All of the other freewheel differentials I've seen have a drive sprocket in either the center or on the end of the unit. The sprocket drives the bolts which mesh with the freewheels The only thing I can think of is because his main concern is driving two...

    Another take on freewheel differential

    So I was doing a search on "atomic zombie" and the following page came up at recumbents.com Triyak The page chronicles the building of a combination trike/paddle boat/kayak but the reason for the hit on atomic zombie was twofold. First he cites savarin's design for a freewheel differential from...

    TiltDragonfly - Tilting Solar Delta Trike

    Based on the pictures on the website the Rohloff is in the front wheel. Looks like he basically has a MBB setup on the front wheel using two belts, one for drive and one for regen.

    TiltDragonfly - Tilting Solar Delta Trike

    So while traipsing through the interwebs I came across the following site about a solar tilting delta trike called the TitlDragonfly. The builder talks about the tilting frame about halfway down the page. Here are some videos from his youtube channel, EcoSunriders

    Viking/Aurora project

    You misunderstood my suggestion. I wasn't recommending buying Hase bikes; I was recommending building two AZ delta trikes of your choice and linking them together with a coupler vice building a single delta style tandem. Going this route you can stick closer to the stock plans which addresses...
