    wheel and tyre to big for the frame can i make room by bending the bars ?

    Is a 5mm wider tyre going to make any difference on wet leaves? In fact is any width of tyre going to make any difference when the lack of friction is between different layers of leaves. A cyclo-cross tyre may give you slightly more chance as your contact points will have higher point loads but...

    Project Brompton Revival

    I used to do that when I was about 10 ;)

    Hello Pedelec community a future E-bike rental place would like your input.

    I live in the North East too (sometimes) I don't know where you are based or what your target market will be. I don't have any personal experience but I do know a couple of people that run bike hire / guiding businesses in the Alps. One of them attempted something with ebikes a few years ago...

    The new best headlight

    So what caused the voltage drop? What happens to the voltage if you increase the current?

    The new best headlight

    The point actually being if the load was as it was supposed to be i.e. 110W at 6.2V the current would be 17.5A which would require at least 2.5 if not 4mm cable. It is all tat that is not fit for purpose! I like the line in the description that says function open circuit, short circuit and over...

    That says input 12v no wonder it blew up! Only getting 6.2v can't have ďone it much good. It also says supports 10w t6 not 11 of them! ;)

    Gear sensor

    Cos you are awesome ;). I suspect that maybe like myself there is a slight almost involuntary "lift" as you go to change gear.

    e-bikes for mountains

    A lot depends on why you want to cycle. If you want excercise then a bike with a torque sensor is best, if you want to go through the motions then a bike with a cadence sensor will do it for you. Are you looking for a bike for off road use or will it all be on road?

    45 Mile Commute, possible on a eBike?

    OP = original poster. As for wear on Eddie's drivetrain, the smaller the sprocket the more work it has to do, that is why mtb often have a steel granny gear and the others are aluminium.

    The new best headlight

    Clearly not fit for this type of use even before things went bang. I was thinking in terms of connecting the light with twisted wires along the lines d8veh was talking about. But I guess the truth is you would probably need at least 1.5mm squared cable if not 2.5 to handle the current...

    Bypass the bms and see what it is like.

    45 Mile Commute, possible on a eBike?

    As the OP hasn't given us any details of elevation change or gradient most of this discussion is meaningless. He is going to lose his licence, is not a stranger to cycling and actually only need a range of 22.5 miles. Any decent ebike with fast rolling tyres and a decent battery capacity will do...

    45 Mile Commute, possible on a eBike?

    Just over 40 miles with 4500 ft of climbing in the Alps at an average speed of 15.5mph on a Yamaha motored Haibike with a 400wh battery. This was with maxxis minion dhf tyres which are not known for low rolling resistance. While the bike is derestricted I was only using low power levels where...

    The new best headlight

    I always prefer to have 2 lamps that are each able to allow me to ride quickly off road (mainly railway lines & fire roads) then if one fails I can carry on. I also prefer to have one on my head so I can look where I'm going which isn't necessarily the same way the bars are pointing. Thanks...

    The new best headlight

    Well done d8veh, mine was tested for the first time last night. Was out for just over an hour, off road most of the time so light was on full. Using it as a head light to complement my Hope4. Found the beam has a good throw and is not too spotty. There is a bright central area with a not so...

    How many people are using there e-bike off-road?

    As long as it makes you feel good. You remind me of someone I used to work with, first time he took us to a proper trail centre he took us straight on to the hardest climb at the place. The rest of us ended up pushing up, the next time I went with him despite being 15 years older I kicked his...

    Just shows how much you need to cheat then doesn't it! I'll flag them again with references to this forum next time I'm on my pc then. You really are a pratt aren't you.
