    Nope, I do not see the resemblance.

    It has finally arrived... Logistics from hell.
    I unpacked the Rumble and put together the bits that needed putting together.
    It had 55% charge, so I did a little test run on the street. It's currently limited, so I will change that later.
    I'm away for a week. I'll sort out reg. and insurance when I get back.
    I'll post a proper review after that.

    Contrary to a couple of comments above neither the Bimota Tesi nor the Britten had a leading link fork. The Tesi uses hub center steering and the Britten is a variant of the Hossack/Fior front suspension. The Rumble has a long leading link fork with the link pivot behind the tire, as in Ernie Earles' patent from the 1950s as used on BMWs and MV Agustas. The Rumble has even greater steered mass rotating around the steering axis than the Earles' fork which probably isn't doing them anything good but it may not be an issue considering the performance envelope of the vehicle. It is an interesting design of LLF, the first I've seen done this way.

    cheers,
    Michael

    No review yet, because I haven't been able to register it. I didn't get documentation from the customs broker. Waiting on Rumble and the shipper to respond... Been a while.

    That's disappointing. What an inconvenience. I hope Rumble helps you out and make it right.

    Doesn't look like Rumble or the shipper are going to make it right... Never again for indiegogo nor rumble motors.
    Europeans seem to have it ok, but not North Americans. Too bad, because the machine could have been a dream but instead is a nightmare.

    So... a quick review.

    The Rumble company is filled with liars. They still say that the bike is able to be imported to Canada... even though Transport Canada says it isn't. My bike somehow made it into Canada, but it cannot be registered or ridden on the street. It's not even supposed to ride on private land. The bike was broken down to parts, but selling them isn't very easy because the performance is crap. Not much demand for a 61.2v, 28.6Ah, 1750.31 Wh battery, 2000w QSMotor, and an unknown 60v controller.

    I did try it out in the neighbourhood. The leading-link steering is horrible. It doesn't feel very stable in a turn. Sure it can be ridden, but it reacts much differently than I'd hoped, and it's not really suitable for a motorcycle. I understand it working with a sidecar. It looked cool.

    That said, the steering isn't an issue because the performance is so poor that you won't get up to dangerous speeds. It's limited, and it's slow. Not sure if that was the battery or the controller or both. Performance seems to be on par with Motorino's 500w and 1500w bikes available here.

    So what next. Parts of the frame are being used for a different project. The original welds were sloppy and weak. One bracket was missing in transit, the only proof of it's existence was a broken weld. The steel from the leading link will be recycled, maybe for scrap, or another project, not sure yet.

    I might keep the speaker system from the "Rumble" just for sh*ts and giggles.

    Overall... The Rumble was money thrown down the crapper.
