Had to warn him his back wheel was on the verge of collapse. I guess the motors do place materially different stresses on bike components. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=19943#post-317609 Tue, 12 Nov 2019 13:29:23 +0000 Darkerside 317609@http://citycyclingedinburgh.info/bbpress/ <p>This article would suggest it's a good thing. I think. My IGH engineering knowledge is about as good as my ability to knit (ie I can just about follow it, providing what you want is a single-colour scarf).</p> <p><a href="https://www.electricbike.com/mid-drive-kit-igh/" rel="nofollow">https://www.electricbike.com/mid-drive-kit-igh/</a> </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=19943#post-317608 Tue, 12 Nov 2019 13:24:43 +0000 Darkerside 317608@http://citycyclingedinburgh.info/bbpress/ <p>Given I've tied myself into mental knots trying to work this out, throwing open to the hive mind.</p> <p>Shimano have a relatively new internal gear hub - <a href="https://bike.shimano.com/en-EU/product/component/city---trekking-e-bike-e6100-series/SG-C7000-5D.html">clicky</a>. It looks like their older 5-gear hub, possibly slightly updated, and certainly rebranded as "ebike specific". </p> <p>Lowest gear appears to be direct drive, and then the rest of the range is 263%. Argument is that it's five more robust gears, capable of dealing with ebike torque much better. Plus you don't need the range of a more fragile hub if you've got a motor helping on the climbs.</p> <p>I can't work out if this is snake oil, sensible, or something else. Is that range workable on a e-cargo bike in hilly areas? Will one break an ankle in the gear gaps? </p> <p>Thoughts? </p>
