The Bafang uses a simple cadence sensor, which measures pedal rotation (and speed). A Decathlon hybrid bike converted to electricĪlthough both motors are similar in many ways, the way they produce electric assist is quite different.

There are two main players in the plug and play mid-drive motor market: Bafang have dominated the DIY ebike conversion kit market for years with their BBS series of motors, and more recently Tongsheng have become incredibly popular with their torque-sensing TSDZ2 motor. A good 250w mid-drive will easily outperform a 500w direct drive hub motor in every aspect. Mid-drive electric bike conversion kits are by far the most refined, in terms of power delivery and efficiency. US Federal law allows up to 750w and 20mph. ⚠Please check the legality of these kits in your country before making a purchase – in the UK and EU anything that produces more than 250w continuous power and 15.5mph (25km/h) is classed as a moped and subject to the same rules and regulations.

So I would guess that we were both hitting the same cadence on both bikes. (Admittedly, there is a major weight and fitness difference between the two gents.)Īlso, as I have a cadence meter on my bike, my cadence on this bit of hill was between 90 and 105. Out of interest, the other "oldie" was on a hard tail with an older model Bosch Cx, and he had no problems climbing the hill. I puffed and panted my way up to the top on his.Īgain, subjectively, there's two of us here who would disagree with you.
We swopped bikes and he "pootled" up the hill on mine in Turbo and bottom gear.
He'd stopped and was getting his breath back before trying to use walk mode up the hill (that's tough with those slopes!). The chap on the Haibike Sduro couldn't do it. Then had to go back down when my "team" were nowhere to be seen. I know it quite well and headed for the top (in turbo). Strava is crap at giving slopes on switchbacks, but the total climb is 111m over 800m, so around 14% average, but with kicks on the hairpins of around the 30-40% mark, where too much power will cause a loop out for the unwary. To add a bit of challenge they both wanted to try coming back into the town via a very steep, switchback road which has been concreted because it's unstable in the wet and slides down the hill (and currently closed to traffic because part of it slid down the hill in last month's storms). Normally I take them on a "mystery" tour but today the wind is blowing a Force 7 and one of them suggested a ride which would be more sheltered. On Friday's I do a "coffee run" with a couple of "seniors" in their 70's.
