    HackD's Tadpole Recumbent Trike build, Mk2

    Steering knuckles pretty much done. Comes to 30" bang-on, as desired, wheel to wheel centerline.

    HackD's Tadpole Recumbent Trike build, Mk2

    One month later, the Steering knuckles are near to done. Just need to drill and tap for fasteners.

    Terra Trike Tour 2 - budget performance conversion.

    "Terror Trikes" ... interesting. I'm a rank noob when it comes to Tadpole trike Geometry, but i've got experience with Sidecar rigs - a mix of Theoretical methodology and invocation of Dark Arts in setting those up, so they aren't 'Terror Trikes'... I assumed that the sketchy handling at...

    Terra Trike Tour 2 - budget performance conversion.

    It's very much velocity contingent, based on a downslope bias. As you put it, it's potentially Oscillation inducing with oversteer. Anything under 30km/h / 20mph - entirely manageable. It gets dicey above that. Routinely reaching 50km/h in those optimal gravity-hill conditions, i want...

    Terra Trike Tour 2 - budget performance conversion.

    Finally got around to finishing off one aspect of the SWB Terratrike - overall Stability/Sensitivity of the front end, which definitely gets twitchy with a dangerous tendency to oversteer and possibly have a CofG shift induced roll-over, if it gets too loose, at too high a speed on steep...

    HackD's Tadpole Recumbent Trike build, Mk2

    Starting to plan out for the Electronics. I insist on having my stuff encased. Can't handle the idea of electronics being exposed to elements/possible soaking, so am following my previous successful test of an enclosed electronics case, as with my Terratrike project. I found an electronics...

    HackD's Tadpole Recumbent Trike build, Mk2

    Getting down to the nitty gritty of fabrication - Old School hand-crafting style. Drill press, hacksaw blade, 1/8" drill bit, break out the section that has been outline-drilled, then file, file, file.. 3/4"x1 1/2" rectangular tubing for maximum strength/rigidity. Fitting into slots, 1"...

    4 Dozen, even, of that type, actually.. most common used are the red shorts Alloy, which come out to about $5.00 per from the cheapest seller on Ali-express. There are 48 of those in the mix (to my count) .. the black stems are slightly cheaper, and i have 6 of those in play at the moment. The...

    HackD's Tadpole Recumbent Trike build, Mk2

    Closer, getting closer to final configuration - obviously, some of my plans are obsolete, some are being realized. It's an evolving design, definitely. One thing is clear - it is going to be one heck of a chain-line involved, including the likely need for sprocket jack-shafts to abruptly...

    HackD's Tadpole Recumbent Trike build, Mk2

    The parts continue to flow in, and the need for additional parts needing to be ordered continues... Fortunately, it's coming down to the cheaper parts and bits and pieces... I received a Terratrike 18" crank boom today that I will work with into the setup.. there will be a bit of additional...

    HackD's Tadpole Recumbent Trike build, Mk2

    Hasn't been much in the way of updates as of late - very much a process of putting things together in certain configurations, taking things back apart, looking at it from a different angle or dimension, and refining. It's starting to get close in terms of general configuration. 48 'red' stems...

    HackD's Tadpole Recumbent Trike build, Mk2

    The 'Project', such as it is, graduated from being a trip-hazard between kitchen and stairs, to being an official "Coffee Table" Imagineering Project this past week. Keep in mind, it's roughed in dimensionally - I plan to narrow up the 'spine' a bit more, and everything else needs to be played...

    HackD's Tadpole Recumbent Trike build, Mk2

    This is actually a hard-shell recumbent seat that i'm utilizing. I've already got one on my rigid Terra Trike - and it's mounting method was relatively involved, requiring significant metal fabrication of seat mounts to adapt to the Terra Trike method of seat mounting. Using this fabrication...

    HackD's Tadpole Recumbent Trike build, Mk2

    Starting to play with the Chassis Ideas... strictly exploration to see fabrication potential. Built in Roll-bar! The bottom and top compound curve pieces are the main parts of a automotive bicycle rack, that i had found curb-side last summer. Reduce, reuse, repurpose! I like the idea...

    HackD's Tadpole Recumbent Trike build, Mk2

    Well, plans are definitely fluid, in terms of shifting goals. I've got lots of Pie in the Sky ideas - but the more i look at things, i am fighting multiple issues - complexity, dimensional vs material limitations, and my own over-ambition. I need to look a this in terms of a modular approach...

    HackD's Tadpole Recumbent Trike build, Mk2

    It's definitely going to be a battle of limited space, ambition, reality vs fantasy design. I rather suspect that i will dead-end on several aspects of my goals, or will need different approaches. I don't think i'll be using near as much bicycle components in fabrication, as i initially...

    HackD's Tadpole Recumbent Trike build, Mk2

    It's been a few weeks since last formal update. I've added my Progress to the above post of my parts ordering, so far. I've been spending a fair amount of time just staring at other's designs, ordering up additional parts, narrowing down what i want in a design. The beauty of the Cain...

    HackD's Tadpole Recumbent Trike build, Mk2

    One engineering path decided on, in part. A 'Cain Hashimoto Starter's Kit' was ordered off of Aliexpress this past week. If anyone isn't familiar with Cain's work - he's building up Adaptive Trike designs - rigid, suspended and leaning/suspended, using largely repurposed Steering Stems in...

    I've noted them also .. that's next level Stupid, in terms of Pricing. As much as i love my Pedal toys, i'd go to a 1-2 year old Can-Am Spyder for a Trike, over that. I do like the concept - as you said, it does appear KMX inspired - which in my books - say's they are padding Profit with...

    HackD's Tadpole Recumbent Trike build, Mk2

    It will be an evolving design exercise, i am sure. I am not sure if i need overly significant Suspension Travel on either front or rear. Given the Terrain demands of it.. i am just asking for an ability to better deal with off road double-track conditions like Pine Tree roots, mud ruts...

    Bear with me.. this is a long introductory post to a new build project, explaining some of my rational for a new project, and explaining the direction i am going in, in terms of design/setup choices and options to be explored. This will be a Project log, in Real Time. How long that project...

    Terra Trike Tour 2 - budget performance conversion.

    That's the sort of Ravine/Trail/Escarpment environment that i enjoy - but that includes rougher trails, and mixed surface paths. Although often double track, the secondary trails are often also rock/root rutted off the main trail AND making elevation changes. As can be seen in that video, the...

    Your Creation's Before & After Pics

    Thank you, Sir.. Variety is the Spice of Life, and Winters can be long and hard here in Canada, on a guy who ain't into Hockey or Snowmobiling. I've got relatively little mileage on the eMTB this season, since the rolling Couch came on the scene - it's THE best way to enjoy an outdoor...

    Terra Trike Tour 2 - budget performance conversion.

    Free Post, with Video link of last good weather ride in these parts. I'm now actively moving into planning out a new build and squirreling parts away, so unsure if will document on this thread, or make new thread. In interests of keeping my projects separate, best i guess to start new. This...
