    Want to verify my frame reach experience

    Are you willing to try a longer stem or even just rotate your bars forward on your current bike and see what the difference feels like? I realise this is not 'the same' as a longer reach, but it might give you an idea?

    Want to verify my frame reach experience

    I'm also around this height (I have measured from 175-178cm) with a larger than normal ape index. I am currently looking for a new steed so have started looking into sizing. The only bike I have ridden for the last 15 years is a 2020 Kenevo S4 (10 years of not riding prior to getting this...

    GOBAO ECVT EMTB Mid-Drive Motor

    Google translate: I have no doubt that the ECVT represents a major technical improvement and is perfectly suited to e-bikes; After all, it only requires one (small ;) ) additional engine; the rest is software. However, like any technological advancement, I think it will involve compromises...

    GOBAO ECVT EMTB Mid-Drive Motor

    I honestly don't know. There are less moving parts, less gear teeth interactions (more teeth that are actually transmitting torque and this is where most efficientcy losses happen, but less overall), maybe less rotating inertia? In the single planetary gearbox, but you also have 2 electric...

    GOBAO ECVT EMTB Mid-Drive Motor

    Thank you for this, it has been on my mind also. I would like to push back a bit here also. I don't think the ecvt will be replacing a chain and deralleur on a non electric assisted bike. On an ebike, different question since we already have one electric motor. Yes the ecvt requires 3 inputs...

    GOBAO ECVT EMTB Mid-Drive Motor

    One again I agree with most of what you are saying. But the details matter here. When charging at the chargers output limit, there is no difference. I should have been more specific for my use of the C rate term here. At the pack level, you are right, it makes little to no difference. But once...

    GOBAO ECVT EMTB Mid-Drive Motor

    Again I agree with everything you have said. I don't work in this area, but experience had told me on the post that higher voltage charging (even at the same power) is both cheaper and faster, even thought both are possible and even done commonly. One simple example is charging 4S2P (4 banks of...

    GOBAO ECVT EMTB Mid-Drive Motor

    I agree that the user does not need to know the difference but there are many benifits to using a higher voltage stem. Generally speaking, almost all inefficiencies in electronics come from heat losses one way or another. Heat losses increase across a system as current increases. So less...

    Avinox Reveals its Motor Gearbox

    I think you might be right. Maybe I was hoping they would be the same.

    Avinox Reveals its Motor Gearbox

    The mounts themselves are different, but they look to be in the same locations? This could shortcut any development required for the frame itself once an M1, M2 or M2S is already proven. And open the door for future retrofits!

    Is this the ultimate bike. 32" front, long travel, gearbox emtb with a removable battery?

    Thoughts on this please? https://www.mi-tech.de/szenario-e-mgu-32/
