    SHTF Ebike Survival

    Wow, nun chucks against a chain is impressive! I am versed in Arnis (Filipino martial arts) but I will think twice with a guy with a chain, especially if the guy knows how to use it.

    SHTF Ebike Survival

    Lol! My noise maker is better than none at all. A 9mm and the right ammo and training can take down a griz: https://www.americanhunter.org/articles/2016/8/10/alaska-outfitter-defends-fishermen-from-raging-grizzly-with-9mm-pistol/ I agree a 12 gauge is better under pressure vs handgun (gross...

    Camping and exploration system with solar charging rig

    RV's are nice but limited on where you can go and park; I like the stealth factor of suvs and vans. I enjoy tent camping, but sleeping inside my suv has some advantages. Last time I tent camped in the desert, I got a snake visit. After I saw the high cost for suv awning, I built the awning...

    SHTF Ebike Survival

    Ah yes, a signalling mirror/device. Good point. I EDC carry a bic lighter already for fire making. I am thinking the lipo can start a fire as well. A broken leg/arm is a SHTF indeed.

    SHTF Ebike Survival

    Great idea on the noise maker/bell and notepads/pens. I am also thinking of a battery powered soldering iron/solder for quick repairs. Last time I crashed, I ripped a wire off. Would be nice for field repair if not too bulky.

    SHTF Ebike Survival

    Yes! Charger for cell phone! I use a 2-6s balancer with a usb charger for this. Hollow points are not advisable for bears; you need something that penetrates their thick hide...I use underwood extreme penetrator.

    SHTF Ebike Survival

    I carry openly; it is legal in Arizona. And yes, I have concealed carry permit. In the woods, I can't be fumbling for my weapon when stumbling on a mama bear. Rare, I know.

    SHTF Ebike Survival

    Ok, the title may be a bit dramatic, but what do you guys carry with you when out riding? My SHTF may be breaking a rear suspension and out 30 miles in the deep woods. I am talking about tools, spares and items you would need to get home. So when I go out in the woods with my e-bike, I...

    Camping and exploration system with solar charging rig

    This is my camping and exploration rig. This is a system: suv, ebike and kayak where I can go almost anywhere; where the suv can't go, it can be reached by e-bike not even 4x4's can't go. The ebike is a downhill bike with a cyclone 3000w motor+48V, 25AH lipo. This is geared for climbing...

    Best Self-Defense for a Lady on an eBike?

    Exactly. Situational awareness and avoidance. I see a lot of cyclist and joggers with headphones on. Easy prey. If everything else fails, rely on your training. If you are carrying a weapon (knife, pepper spray, glock), I hope you train with it.

    Lots of punctures - replace with solid or puncture resistant

    As others have said, solid tires don't ride well. I have very good success with dual ply downhill tires and gone tubeless. I think if you look into dual ply 29inch tires, there may be some choices like Maxxis minions/holly rollers. My bike sees almost weekly offroad and commuting 24 miles...

    RC assistance

    two56, Very elegant design; do you expect spin out issue with the one way bearing because it is only pressed in? Looking forward to your testing!

    Yet another Lipo Fire

    Yes, Dogman. I had it taped up and the bottom/top of the steel enclosure has a rubber lining, but sides are bare steel. It was not a tight fit. Earlier that day, I had ridden it quite roughly and may have had the cells rub, causing a short to occur. There will be no more lipo around the...

    Yet another Lipo Fire

    I was fortunate it was at least 8 ft away from the walls. I did not see any smoke damage other than some soot on the walkway tiles. It cleaned up with no visible damage with water and a little green scouring pad.

    Yet another Lipo Fire

    While at out of the house today, my neighbor called me regarding a thick smoke coming from the front of my house. As I raced home, 3 fire trucks, a police car and the fire chief were in the front of my house. A good neighbor passing by had noticed the thick black smoke and called the fire...

    Yet another friction drive

    Hi EVTodd, The ESC I am using is the Turnigy AE-80A. It is capable up to 6s lipo only. See below spec from Hobby King: Output: Continuous 80A, burst 95A up to 10 seconds. Input Voltage: 2-6 cells lithium battery or 5-18 cells NIMH battery. BEC: Linear 4A @ 5V I like the 6s lipo...

    Yet another friction drive

    Hi EVTodd, Yes it is correct; when throttle is off, then drive will turn with the tire and therefore the motor is a generator. I worried about this; but after 6 months of riding this design, I have not blown an ESC yet. Perhaps I am lucky. However, I don't ride it without throttle...

    Yet another friction drive

    Hi footlose, Engagement is done by pushing the arms back until it contacts the tire. Once engaged, it does not come off until I push it back forward again to disengage. The spring there serves to keep the roller from dragging when not engaged. I think crossbreak had a design where he...

    Yet another friction drive

    Hi Guys, I have been testing this home made friction drive to see if it could replace a hub for as an assist for commuting. Inspiration came from the friction drives here in the ES; I have put my own design changes to suit some goals. First, instead of using knurled roller and one way...

    Sanding/Turning/Sawing/Wood Turning/Drilling/Milling tool

    The lathe milling attachment has a work area of roughly 2.3"x1.75". However, with careful planning, you can shift the work to mill a larger area. You can of course drill with a lathe; you can also fly cut, slit, mill, etc. The lathe can do work that is hard(er) to do on a mill; for example...

    Sanding/Turning/Sawing/Wood Turning/Drilling/Milling tool

    Hi Cwah, For not much more, you can get a kit form of the Taig lathe (K1019) It is about $163 without the motor. I use a brushless motor--a 63mm turnigy, this way it is compact. Here is mine showing the relative size to a small water bottle. Unlike the multi-purpose tool from hobbyking...

    Welding

    Hi heathyoung, What do you like or dislike about MAPP gas? How's the braze quality and finish? If I end up doing GAS brazing, I may have to use MAPP vs acetylene due to HOA/insurance concerns. I also like quality and look of tig welds. I am thinking perhaps starting with gas then tig as...

    Welding

    Hi Guys, I am looking to start learning how to weld. I want to learn to weld in order to start modifying or building steel frames. There are different process out there: GAS, TIG, MIG, ARC. Pros and cons when used in frame welding? People modify and build their own frames here, what do...

    Life span of a hub motor?

    I rode a 1kw BMC direct drive hub for over 10,000 miles (16 kms) until it was stolen. I think it would have lasted 10,000 miles more. I rode it conservatively at maxing 500-1200 W in hot/shine weather in Phoenix. I replaced parts of the bike (controller, battery, a set of chain, pedals...
