    Built an e bike. Is it okay fir the axle to sit in the dropouts like this after being torqued down?

    For use with other than low wattage hub motors the tab washers are basically useless for most installations due to the bikes dropout structure vs. the potential torque output of the motor, especially one over 1,000w. But there are plenty of aftermarket torque arms available that will connect the...

    The leader in hub motor knowledge and components is at ebikes.ca. Justin at Grin has done more to develop hub motors than anyone for the DIY sector and is very free with his conclusions that he posts on his site. Check there to at least see what is perhaps possible?

    Hello from Cape Cod

    A relative had 3 cottages in Eastham that we would go to every summer for a week growing up in So. VT.. Always brought my bike and rode all over. Way before e though! Last time I was on the Cape was 20yrs ago and even then the traffic had gotten bad so it's good they are putting in bike...

    Spray-based chain lubes?

    I have been using Boeshield T9 for many years to maintain the various bikes that I've had to look after. Wax based and no need to clean just apply, back wipe and go. 12oz. spray can lasts well over a year for two bikes.

    Has anyone tried building a hub motor wheel with your rim? Is it complicated?

    Seems like you might be confusing straight pull spokes with spokes that aren't crossed and thus go straight from the hub to the rim and is popular on some hub motor/smaller wheel combinations? With larger rims using at least a 2 cross pattern is preferable. The Grin calculator mentioned is a...

    With 125% tariffs, will the e-bike market die?

    "Trump IQ at least 156" :rolleyes: And he is 6' 3" and weighs 220lbs. And can pass cognitive tests standing on his head but just don't ask him what the name of the test is.

    ToSeven DM Series Mid Motors

    Pedal management via ratcheting with instant engagement works better for me at least it always has even pre e? However the onboard throttle I have could do the job if I ever cared to use it for anything other than taking off and a walk assist.

    Brose sold to Yamaha

    While I haven't seen it confirmed yet I think that Brose lost its S Levo contract? That alone would be good reason to cut it from their portfolio regardless of any sort of tariff pressures. Surprising though that Yamaha took up the mantle as they already have a pretty solid motor system to offer...

    My DIY builds: GMAC, BBSHD, 9C RH212, CYC Photon, ToSeven DM01

    SHG, I was an early adopter of 2170 cells as I thought they were perhaps marginally better for use in eBikes. I am going to put an emphasis on marginally.....as time has gone on for sure companies have adopted them and why not as margins are good for business. But if as you say your current...

    Bafang Ultra Greasing Gears

    The properties of CornHead grease are such that it turns into a thick oil while in use and resorts back to a grease when not. So it doesn't matter where it gets put in the gearbox of an M620 as it will distribute itself when it liquifies under use. The thing that I personally have found works is...

    Small low pressure pump?; I

    You do realize that even though 5 and 3" tires may run best at low psi that it is actually the volume of air in them that you are messing with? So I would suggest you change your search from a low pressure to as small of a HIGH VOLUME pump as you can find. The Wolf Tooth Encase 40cc is one...
