Yes new chain anyway as it 11 speed, the derailleur I did have to buy new. It’s a RD-M5120-SGS.

The existing cassette is an Shimano Alivio 11-34T Shimano Hyperglide (HG400 I think) and I have a near new Deore 11T - 42T CS-M5100 I found to go in. I've halfway through upgrading the brakes to Deore M6100 with new Ice tech SM-RT86 rotors. Then I'm trying the smaller chainring then make the final call on migration to 11-speed shifter, chain, and cassette.

Wouldn’t an Apple AirTag at 30 quid be cheaper and longer lasting than a tracker? I have one in my suitcase and it works very well.

Thanks both for the suggestions. Will try the chainring first. [mention=3847]saneagle[/mention] I did try the throttle but it seems to deliver power in bursts. Something to explore a bit more. Also, a helpful person on the Wisper support email told me my S/N means the frame was built in December of 2020 and would have shipped in 2021. Hence the 2012 start of the serial number.

My wife’s Bosch powered Allant occasionally has this issue. It only seems to happen if you insert the battery and then try and turn it on immediately. Instead, if you connect the battery and wait five minutes before turning on the LCD it seems to come up OK.

I picked up a pretty new looking Wisper Wayfarer M7 with the 700 Wh battery via a local auction site for around £1,000. I'm really enjoying it so far! Is it possible to work out the build date from the serial number? It’s SKMBG201225xx. Living up a steep drive, more than half a mile of 12% average (1 in 8), I need to be in first gear to get up here and even then with some effort the best I can do is about 9 kph (5 mph). I've been wondering about swapping the chainring for something with slightly fewer teeth. Currently the m7 I have is fitted with a 104mm BCD 44T steel chainring and I'm going to try a Truvativ 42T steel single speed which was cheap as a quick test. Would people recommend this simple swap (mybe to 40T) or a more extensive change to a 1x10 with a replacement cassette with more teeth on the biggest cog? Top speed is not a great priority, 32 kmh (20 mph) is plenty for me and I can easily exceed that with the present chainring and 300W NZ settings on the flat. I appreciate for a 1x10 change out that a new chain, shifter, and maybe a long cage derailleur might be required.

Greeting from sunny New Zealand where it’s currently a balmy 30° C / 85° F. Own a few human powered bikes including a 26" Tange steel MTB that I've owned and ridden from the '80s, a reasonably modern 29er alloy frame MTB, and 700C road/ravel GRX equipped Surly steel frame bike, and now a Wisper Wayfarer M7. I enjoy working on and upgrading bikes, in many cases slowly swapping parts to move up the Shimano food chain. I like to buy everything at auction (except for tubes and tyres). My wife rides a TREK Allant+ 7S step thru with the Bosch Performance Line Speed mid motor and I find it a bit hard to keep pace! Anyway, I picked up a pretty new looking Wisper Wayfarer M7 with the 700 Wh battery via a local auction site for around £1,000 and that pushed me to sign up. Tyres are presently CST Rock Hawks so I'll be swapping those for Schwalbe Big Ben Plus tyres for a the road biased riding I'm expecting.
