Long time lurker here, looking for some guidance on a DIY build I want to start planning for (or potentially something custom from a builder). I am an esk8 noob, but coming from e-bikes/RC/etc/etc, I'm familiar with all the common components and I used to skateboard as a kid (generally cruisers) and limited experience w/ a cheap hub motor board, but am looking for something a (lot) bit more heavy duty. However, now that I start considering all the build options, I'm getting stuck in a bit of analysis paralysis and could use some input from the experts. I'll have to apologize up front because this could get a little unwieldy since I'm kinda scatterbrained and I'm stuck on step 1 :). I'll try to organize my thoughts to start w/ though...
- Context -
- Max range/battery... like a kWh @ 10-12s, if I could
- Torque > Top speed
- Confidence inspiring/stable (...up to a point)
- Weather resistant (if possible)
- Bonus points for hybrid-able (switching back and forth from 7" pneumatic to large urethane wheels).
I would like this to be an alternative commuter option for me. My commute to work is 15 miles each way and it is is mostly well paved trails and side streets, but there are some bumpy areas, rocks/leaves/grass/etc, and some more rough transitions between trail path and streets... but nothing as extreme as a mountain bike/off road trail (that could be fun too... just not a core requirement).
I'm pretty active, but I'm built like a fat, brick shithouse and am pushing 3 bills, so I need everything to be pretty stiff as well. I want something I can cruise around on effortlessly and can tackle modest hills without pushing the motor to it's limits all the time. I want something that can hit 20+ mph pretty easily and can handle the distance w/o draining the battery (I'd ideally be charging from 20% (or more) back up to 90% (or less) to extend the recharge cycles (with an occasional charge to 100% for cell balancing)). I know my extra weight is going to kill efficiency (and speed/range), but I don't know if that means targeting 30+ mph at 80% efficiency 20+ at 50%, etc.
I'm sure I could get by with a board and some bigger urethane wheels, but since the path is a bit rough here and there, I thought some AT/pneumatic wheels would make the ride more enjoyable. I was originally inspired by the Evolve AT setup and was thinking I'd try doing a quad 200kv 5065 setup (vs. their dual ~140kv setup... since those motors can be purchased for so cheap) and do a beefed up custom longboard version of their AT models... but then as I started looking around at more AT stuff, I came across Trampa boards which threw a wrench into my plans :). (the holypro urban carver is the leading candidate)
I don't have a specific budget in mind, but I do want to stretch my dollar where I can and get the most for my money. I can't go completely crazy... but I'd say $2k-$3.5k as a rough guideline, depending on much it can meet or exceed my targets and what I'm getting in return.
I know the trampa boards can make smaller turns and can carve more aggressively, etc, but I've read conflicting info re: people who think the suspension fixes speed wobble vs. others that complained about feeling uncomfortable at higher speeds. Can anyone speak to the riding characteristics between a standard longboard (something like a Comet FSM 2, etc) with AT wheels vs. a trampa board with the same wheels/truck width? IE: Ride quality/stability/enjoyment/limitations/pros or cons for bigger riders/etc.
Are pneumatic tires overkill for my situation (and should be limited to MTB trails, offroading, etc) or a good option for me? Assuming I go 7", high PSI, without a lot of deep tread: is the rolling efficiency comparable at all? Any issues with them feeling 'bouncy'? I only have experience with polyurethane wheels. I would like the setup to be hybrid between small pneumatic and large polyurethane, but I'm planning to build it out initially as pneumatic as the primary (as of now).
Are there any custom builders who I should consider who specialize in this area? I've tried reaching to a couple w/o luck and a couple others I had issues w/... either because of lack of responsiveness, outdated info, or over-inflated costs, etc. I'm willing to pay a bit of a premium for a professional, but that only goes so far.
If I do go the Trampa route, what are people's thoughts on just buying their deck vs. going for their semi-complete esk8 boards? IE: what are your thoughts on the 136kv motor + mount that comes in their esk8 kit? Decent value? Overpriced? ...and maybe a stupid question, but what's with all the different 'premium' ($$) mounting offerings (that aren't in their 'completes')? I'm not clear on what differentiates one from another. Does the extra rigidity increase efficiency... or other? Why not just go w/ the cheap one (I mean... if it fits...)? Would it be better to buy the motors/mounts separately?
...I think that's it...
Anything else I should know before I start this project :)?
This turned out to be a longer post than I was expecting, but if you made it this far... thanks!
