    Japanese government reacts to Chinese high-speed ebikes

    Hmm I wouldn't say that these are "gaining popularity" unless that means going from 0% of people to 1% of people. 99% of people will just buy from one of the big three. Some people will buy some cheap foreign bike off of Amazon, etc., unaware that it is illegal. Also, this is not about...

    Should it be legal for kids to ride ebikes?

    Technically the wattage isn't limited by law, by but almost all PAS bikes are 250 watts. The power output is, however limited to twice the rider's power up to 10KPH, and it drops from there down to zero when you hit 24kph. For this reason, throttle ebikes aren't legal and nobody bothers with a...

    Should it be legal for kids to ride ebikes?

    It really depends what an "Ebike" is. In Japan, the term had no legal meaning and had only been used in the last few Years to denote spotry ebikes like the Yamaha ypj and manasoc X lines. The PAS line in the pictures above, and almost all other bikes with a battery in Japan are much more...

    Yamaha YPJ-MT Pro

    I agree, the MT Pro does not share things like motor temperature, assist mode, etc. But those things *could* be shared with Bluetooth or ANT+. Historically, bluetooth took more power than ANT+, so it was popular for things like heart rate monitors and speed sensors, but with BLE that is...

    Leomo Type S Bike Computer Review

    I am posting here because although it's bike related, it isn't eBike specific: I was looking for something like a hybrid between a Garmin Edge and a smart phone. Something with decent navigation and voice prompts, that would let me listen to music, while also giving stats like speed, cadence...

    Yamaha YPJ-MT Pro

    Not sure exactly what you mean: The bluetooth settings on the bike are: CSCP (Cycling Speed & Cadence Profile), CPP (Cycling Power Profile), or Off ANT+ is sadly not listed as a feature on their page, in the manual, or anywhere in the menu. That said, one of the main advantages of ANT+ is the...

    Yamaha YPJ-MT Pro

    It's worth noting that the bike has two bluetooth modes (profiles). According to the manual, one can show speed and cadence only, while one can also show power. I think the edge would only see the bike when it was in the mode for speed/cadence only. The fields I am using were the existing...

    Yamaha YPJ-MT Pro

    BTW I have got some new upgrades recently, the first of which is a Supernova M99 Pure Mini. (I made a separate post about that, but the link to my blog is https://shiruba-technology.blogspot.com/2021/07/supernova-m99-pure-mini-u-boxing-and.html. ). I have tested this and it works even with...

    SuperNova M99 Pure Mini - Initial Testing

    Hi everyone, I recently purchased the SuperNova M99 Pure Mini as an upgrade for one of my eBikes. I have unboxed it and tested it a bit, which you fan find more about here: https://shiruba-technology.blogspot.com/2021/07/supernova-m99-pure-mini-u-boxing-and.html One interesting takeaway is...

    E-Horn?

    That one looks like just the cheap moped horn (the same as you'll find inside the juiced alarm horn), but with a special mounting bracket. You can get the base horn super cheap - it's just that it needs 12v with a large amount of current. Example...

    E-Horn?

    Mine should arrive soon (also from bike 24 international shipping), and I have no idea how to hook it up, but I do know I will be opening up my Yamaha anyway to install the supernova light I also ordered, so I will see what I can do then. I couldn't find any installation manual online, but I...

    E-Horn?

    By the way, I didn't mention this before, but if you have a really loud horn for road use, you should probably also have a normal bell for trail use. I try to ride on the road whenever I can, and in places where everyone is going 50kph, they are not going to hear a little "ding ding" sound -...

    E-Horn?

    More to the point, most of the are a bit uhm.. well toy-like in their construction. Before buying the Juiced one, I bought some random one from Amazon. It was actually plenty loud, but ran off of replacable AA batteries, and was made of cheap plastic (ABS?). Given that it will be outside...

    E-Horn?

    Hi, thank you, that is very useful. They don't seem to ship to Japan, but I assume I can find a similar product locally. I was thinking of using one of those drink bottle covers and cutting it in half, etc.

    E-Horn?

    Hi everyone. By the way, I have two of the Juiced bikes horns, which are somewhat different from each other. The old one came with a plastic mount and has a micro-USB charging port. The new one has a metal mount and USB C charging. The reports look the same (black and metal, not white like...

    Options for clip-on kickstand?

    Oh I forgot to mention, depending on your bike, the following might work: http://www.minoura.jp/english/rack/kickstand/phs-1.html This requires bottle mounts on your uptube, or you need to add them with something like this...

    Options for clip-on kickstand?

    BTW I bought the Luna stand, and it worked great.. until the tab broke. They don't sell just the tabs, and in fact they don't sell the peg leg anymore. I don't think Corki is an OEM or actually manufactures anything, they just sell the same thing that 100 other companies do. More to the...

    Yamaha (YPJ) cross core \ cross connect speed limit mod sold in Japan

    Hi, Just a quick glance at the text, but that person is selling a lot for more typical Yamaha bike sold in Japan (the PAS line, not the YPJ line). Those trends to have an optical or magnetic sensor on the outside of the hub. This means they are easy to defeat if you just change that ring...

    Yamaha YPJ-MT Pro

    Will the main one is a USB powered light, since it doesn't come with a built in light. If you want to do mountain riding at night then you'll want something more powerful than USB can power, but the light I found on Amazon works fine for trails and makes it road legal at least. Also, you can...

    Yamaha YPJ-MT Pro

    At least my Garmin 1030j connects and shows the speed and cadence. I haven't tried the other mouse which also can show the wattage.
