    I had my first flat. Had to pull the motor, ha! Fifteen minutes and back to wreaking havoc on the trails.

    I'm not so sure about that. Young men are probably likely to see these bikes more as a cool tech gadget than a traditional ego-puffing set of wheels. It's a different mindset, which is demonstrated by the fact that this segment gets much of its mainstream coverage from sites like Engadget and CNET.

    I've a friend who bought the RadRover. I rode it and it's a blast and what I will hopefully be putting in the stable this summer.

    He had one problem with the battery and connector about a month after his purchase. He said RadCity was very helpful and responsive to his issue and took care of him well.

    Too funny, I too had my first flat on my Rad Mini last week! Luckily I was home, so I got put it on the workstand to change the tube out. Pretty easy once I got everything lined up. I did have one fubar moment when the spacer washer that locks into the brake side dropout fell off onto my bench. When I put the wheel back on, it was binding like crazy with that spacer missing.

    Other than that, I completely love this Rad Mini! My high end pushbike sits idle because the mini is just so much fun. I have a 12 mile bike path loop in my neighborhood that meanders along the Santa Ana River with plenty of off road options too. The mini is getting ridden daily.

    So far the needed upgrades have been a good set of RaceFace pedals (stock folders way too small for size 12's), and a RaceFace 350mm seat post with a twin bolt clamp (the stock 300mm post was at full limit and the clamp creaked under my large ass), and some bolt on Ergon grips since the stock leather grips kept rotating and bothering my hands. I had to cut down the throttle side grip, but easily done since the Ergon's bolt on the outside edge.

    Does the Rad Mini have more torque than the other Rad City bikes? The smaller wheel size? Maybe I should have said more bottom end?

    I have not ridden any other models of Rad, so I can't tell you. I will say that the mini is plenty zippy and moves right along in PAS5 to cruise at 20mph if you want it to. Most all of my riding is in PAS 1 or 2, and the assistance is just enough to offset the weight of the bike. Throttle is great for zipping across busy intersections, starting out, or gettting up a quick hill.

    To get home, I have a 2 km long 8% hill to climb.

    Will that 500w motor in the folding Rad pull that hill?

    I believe it is a 750w motor.
    BTW 2017 Radwagon for 1349.00.

    Reason I was asking about the Mini - is it is a geared hub motor. The Radcity says brushless direct drive. Seems a youtube said on another bike that geared have more torque but louder than dd.

    3AF5CA16-A614-4A96-A148-30F4A3CE4185.jpeg I got another farkle for my Rad Mini today. A 3D printed thumb throttle from 1859 Northwest. Just took a 10 mile shakedown ride and the thumb throttle is a nice improvement over the twist grip.

    It has a small Velcro strap and is easily adjusted. It even comes in black/orange to match the Mini.

    Proud owner of a 19" Radcity. Bought mostly in case I get the hankering to build another bike frame, it's the cheapest way I've found to get all the needed parts. For now, happy just zipping around.

    The whole e-bike / e-motorcycle market reminds me of the early days of the automobile. Tons of start-up's and other small companies with interesting designs.

    My main concern at this point would be long term durability/support. If I spend $5-10k on something I want to know it will last for years. If a small company goes TU or a proprietary battery is NLA you have a expensive boat anchor.

    For similar reasons I held off from purchasing a recently discontinued Brammo/Victory Empulse last year. Was tempting as the price was marked down from $20,000 to $10000, but the battery tech was based on 2013 chemistries and the added complexity of the proprietary 6 speed transmission had me holding out for a Zero or an Alta. Turned out to be a good move as Empulses have dropped another 35% in just one year with remaining stock going for around $6500 and Zero and Alta have increased performance and lowered prices.

    I believe the industry is within 2-3 years of hitting that sweet spot of selection, performance, price, quality, battery standardization, charging infrastructure, and dealer support for wide adoption to occur.

    I’m interested in seeing what the traditional manufacturers will bring to the fray, especially with the recent Alta/HD partnership. Hopefully it doesn’t go the way of the Brammo/Polaris buyout. Because of that aweful result, I’d almost rather see a company like Zero remain independent than be bought out by a bigger fish. It’s harder for bigger fish to change directions while smaller companies are willing to apply the greater risk/reward card. Seeing Vespa, HD, and Honda get into the game though lends confidence in the future of EM’s. I like that Honda has bright along side it’s all electric scoot, a hybrid version, to balance out the need for range until high speed charging infrastructures can satisfy those needing to travel outside of their immediate areas. The next few years will be interesting for sure.

    Startups like Neematic seem to have a strong enough following (if they don’t price themselves out of business) by offering what Alta, KTM, and others currently aren’t. Their bike strike a nice balance of power and weight for agile trail/MX applications - I believe bikes of this type are poised to do very well in this segment and we will see many more like it in the years to come.

    Specialized already has Vins on their ebikes. Don’t know if they get registered in any States but they have them. Or at least I saw them on some of the early ones. Nice bikes too.

    Looks very cool. Don't get me wrong but I'd like an e-bike that looks like a 70's moped with a 50 mile range and 30-50 mph top speed.

    I'm not completely clear on the details, but there is a difference between a serial number on a consumer product and a VIN on a federally approved vehicle. An ebike with a max speed of 20 mph or less unassisted and a motor rated at 750W (1 hp) or less is federally defined as a bicycle, which is a consumer product. If it exceeds those limits and is going to be used on the street, it needs to pass Federal Motor Vehicle Safety Standards (FMVSS) for motorcycles, mopeds or whatever. Then it gets a VIN, which will be linked to the manufacturer when an owner goes to register it. Insurance companies generally need a VIN too.

    If a Neematic was to be used on the street, its 15 kW (20 hp) motor would make it a motorcycle, pedals or not.

    BTW, I just looked at the Specialized site, and there is no mention whatsoever about whether or not they meet federal limits. No power ratings, no current limit, no nothin'. What the [bleep] is that about?

    They say:

    "Yamaha Power Assist Bicycles have our PW and PW-X center drive motors which operate with pedal assistance. By placing the motor low and in the center of the frame, the rider has greater control over the balance and maneuverability of the bicycle.

    In addition, the integration of the motor as-one with the drive train increases the amount of torque. That power assistance, paired with the rider’s pedaling motion and quiet design elements, result in a natural assist which feels like an extension of themselves and not a mechanical influence on their bicycle.

    So how does it work? Simply stated, these motors engage only when you are pedaling. The technology inside measures the rider’s pedaling force, the bicycle’s rolling speed and the RPMs of the pedals, then adds the right amount of power into the drivetrain. The level of power assist that the motor puts out is up to the rider and can be adjusted on-the-fly."

    No prices or specs on their site...

    The first generation turbo Levos that I saw had a VIN where the other bikes had a serial number. And I mean it started with VIN........
    Never saw a title though so not sure what it was about. Maybe they planned ahead in case it was needed. They were pretty early to the game.
    The Vado I looked at yesterday had just a normal serial. No vin.
