I've always wanted to swap out the generic Genesis Tomahawk electric longboard deck with something smaller - like the Hi5ber carbon fiber Ion 30 mini cruiser deck. Check out the results!
As Spring approaches, so does my infatuation with electric skateboarding. This year, one of the most anticipated complete boards birthed from the DIY ESK8 scene - the Carvon EVO and REVO 4WD is ready to launch on Kickstarter.
As one of the earliest vendors in the game, Jerry Palacio, Carvon’s founder - has been in the hub motor business for quite some time and it shows. From his unparalleled customer service to his patience with even the most demanding users, Jerry’s passion for ESK8 is reflected in his constant hub motor innovations, birthed from his workshop in California.
The Carvon V2 and V2.5 hub motor kits have been a prominent mainstay in my local electric skateboard group for the simple fact that they can take a major and I mean MAJOR beating.
From single digit weather and truly harsh road conditions (gaping potholes, salt, gravel) in and around Michigan, our Carvon motors have never failed. As our experience grew, we began building our own VESCs (Vedder Electronic Speed Controllers) and battery packs but the one constant for drive train systems are Carvon hubs. They just never fail.
The arched "drop down" shape of the deck is meant to position the rider close to the ground for better feel and performance
With the Carvon EVO featuring the new V3 Dual Direct Drive - the motors are no longer sitting inside of the wheel. This direct drive layout eliminates the need to bore into the wheel which allows thicker urethane for smoother rides and also reduces stress on the motors. Best of all - and this is such a sleeper feature - the wheels can be replaced! From authentic ABEC11 Street Wheels to MBS All Terrain Wheels to Pneumatic Wheels, the range of options for a drive train system that isn’t a belt drive is incredible.
Carvon's Kickstarter campaign is very close to its $49,000 goal, which means that cheaper pledge/reward options like the $999 EVO and $1,499 REVO 4WD have all been reserved. The $499 V3 motors are still available, as are the $1,099 EVO and $1,599 REVO 4WD. With our help, V3 shipments will start in May, EVO shipments in July and REVO 4WD shipments in October. Retail prices are estimated at $599 for the V3 motor kit, $1,499 for the EVO and $1,999 for the REVO 4WD.
Ever wanted to make a DIY Action Cam Backpack Rig without having to watch a long, boring tutorial? Well now you can!
My original DIY Electric Mini Cruiser Skateboard still holds up quite nicely even after 6 months of hard riding and natural wear and tear. But as with all things DIY, parts can always be upgraded. One key feature that I wanted to improve upon was weight, so once again, I researched the right combination of components to make an already awesome commute even better. I've nicknamed this build - the A2ESK8 Mini Cruiser.
My original 29" mini cruiser was the perfect size thanks to the unique design of the now discontinued Jet Spud deck. But I wanted to do something different, which is why I chose the Hi5ber Ion 30 mini cruiser deck. Hi5ber has built a great reputation for manufacturing the best carbon fiber longboard decks available. They are lighter and stronger than typical wooden longboards which create a more controlled, responsive experience for the rider.
The Ion 30's design is the definition of stealth with it's ultra thin rails that gradually curve thicker towards the wheelbase. The added benefit is an enhanced wheel clearance that looks so damn futuristic. Other than the low weight, the characteristics of the Ion 30 include high rigidity, high tensile strength, corrosion resistance and fatigue resistance. And unlike wood, carbon fiber doesn't warp when exposed to water.
Before electrictrifying the Ion 30, I tested it out with Gullwing Sidewinder II trucks alongside 72mm ABEC11 Freerides and it was a blast. That combination of an ultra lightweight carbon fiber deck and double kingpins was so much fun I was a little hesitant to throw electronics on there. But my curiousity got the best of me so I got to work.
The next step in weight reduction was the battery. My original build contained the 10s3p Enertion Space Cell, a wonderful battery pack, but 30 cells demand a lot of real estate in the wheelbase for a small mini cruiser deck. With a wheelbase of 16.25" on the Hi5ber, I knew I had to figure out another power solution.
I ended up creating a custom 12s1p LiFePO4 battery pack with the help of my friend Landon who is an electronics wizard. LiFePO4 batteries are the safest type of lithium batteries as they will not overheat, and even if punctured they will not catch on fire. The cathode material in LiFePO4 batteries is not hazardous, and poses no negative health or environmental hazards. Due to the oxygen being bonded tightly to the molecule, there is no danger of the battery erupting into flames like there is with lithium-ion. We used 12 cells in series for a total voltage of about 36v. Paired with a BMS, voltage display, charge port and power button, the pack ended up having a more compact size - perfect for the Hi5ber deck.
Once again I designed a custom 1/8" ABS enclosure using my homemade vacuum former. This time I wanted the buttons to be located on the side of the enclosure as flush as possible. This created a more pleasing appearance that complimented the look of the carbon fiber. The length of the enclosure came out to 11" and width at 5". This meant plenty of room to spare on the Ion 30 wheelbase.
Another big upgrade I made was swapping my original Torqueboards 2.4ghz Mini Remote with an even smaller 2.4ghz Nano Remote that features a thumb throttle instead of a trigger throttle. As far as how it feels in my hand, it's pretty awesome. Granted, I'm not a big guy but it's the right size for stealth in the city. It's as if they took the best features of the Yuneec EGO and Boosted Boards remote and put it into a no frills casing. I like the short throw, knob throttle which is a much better design than Boosted's long throw thumb dial and trigger button. Shout out to Kaly over at ESK8 builders for the hookup on this remote.
The only components I ported over from my original build are the Ollin Board VESC and the Carvon V2 Single Hub Motor. Because of months of wear and tear and a few moisture issues, Landon and I decided it was best to clean the VESC up with some gentle scrubbing and a coating of anti-corrosion spray. Even so, the VESC is still going strong with no issues or errors - a testament to Ollin Board's high quality manufacturing practices.
My Carvon V2 Single Hub Motor was upgraded with authentic 90mm ABEC11 Flywheels and is really the backbone of my entire mini cruiser build. I've put the hub motor through the ringer in every harsh road condition imaginable and it continues to perform flawlessly. Carvon continues to push the boundaries of eboard drive trains and I look forward to seeing what they do next with their V3 hub motor design and EVO series.
Dialing in the VESC settings is critical for creating a safe and fun mini cruiser. My original build was capable of hitting 31 mph but the sweet spot for a board this small is around 15-18 mph - more than enough for carving through a dense city filled with intersections and pedestrians. Also, the 12s LiFePO4 battery delivers a stronger punch than my 10s lithium ion with a more stable discharge and minimal voltage sag. As much as I enjoy releasing the full power and speed from a DIY eboard, there's something quite satisfying about taming a mini cruiser eboard that has the ability to hurl you but won't because you're keeping it on a leash. More importantly, this build never feels like it's struggling or straining and that kind of confidence transfers into longer range and fun, safer rides.
Skating the A2ESK8 Mini Cruiser around the city proved to be a blast. On FOC mode with the Carvon V2 hub motor, the sound is nearly silent. The ultra light Hi5ber Ion 30 board makes acceleration from standstill fantastic and it really feels like your riding on some kind of space age material because of how responsive it is. Carbon fiber handles bumps slightly differently than wooden decks but in a good way because vibrations don't transfer as much harsh energy to your body. Oh and did I mention how light this thing is? Seriously I'll take carbon decks over wood any day of the week.
DIY electric skateboard builds have been getting better and better in just a few months yet there are still just a handful of 30" and under DIY mini cruiser builds. Perhaps it's a bit of a stigma to purposely limit your top speed on a smaller deck but I feel like it's our responsibility to be ambassadors of this technology everytime we step on a board. I've already seen friends who've hurt themselves on eboards and in almost all cases, the problem was either an inexperienced rider or a road obstacle and not a board failure. Going over 25 mph instead of 13 mph on a non electric board meant crashes that have caused broken bones and serious concussions. Believe me, I've had first hand experience with this and it's made me a very visible advocate for eboard helmet safety.
This mini cruiser was not designed to be a land missile and it shows. It's become the ultimate conversation starter whenever I ride in the city because I'm seriously just having fun. The weight reduction made a huge difference and carrying it on public transportation is even easier. If you're in the Detroit area at the end of July, check out this mini cruiser build in person at the Detroit Maker Faire where will have an A2ESK8 booth and demonstrations.
