You obviously haven't tried this one: https://www.bumm.de/de/produkte/akku-scheinwerfer/parent/192/produkt/192qmla.html? No, I didn't pay that price, about 40€ IIRC. I slip mine off and put it in my pocket where it makes a handy torch on unlit footpaths. I also have this one...

[multiple power cuts are making editing this "complicated"] No. Controller LVC at 30v and BMS minimum of 27v-28v for a 36v battery means you have plenty of Wh for lights before everything switches off - at a minimum about 20 Wh.

The cassette arrived and it looks like, well... I paid 19€ for it and not $50 plus postage I have a few days off work and would like to test ASAP but as usual when I have a few days off there is no weather window, even for a 15 minute ride :eek: Here is a look at the difference with the 11-40...

1. forget about using the output from the controller, hardwire the headlight to the battery, battery off = lights off. Run the wire to the tail light from the Avy E, don't get polarity wrong. Best case scenario it won't work, worst case the buck converter will go pop. 2. wire the trailer lights...

The Avy E is a bit weak in my opinion, I also have a 40 lux light I use around town but wouldn't go on the open road with it, especially on the trike. Even 70 lux is a bit touch and go on that though it does make me slow down at night... Your 42v max light should work up to 50v, mine does but it...

The best place for the battery is under your backside but often there isn't enough clearance there. MarkS of electric trike fame has his slung off the back of his ICE trike seats. If I ever put the GSM in the front I think I'll make a battery holder that goes under the frame between the front of...

Example: The other day I had to go pick up some battery bits from the package reception place. Imagine a slight downhill section of road limited to 30 kph with speed bumps. A BMW caught me and thought about passing just before the first speed bump, he braked, I jumped it at about 38 kph. By the...

I peak at 44 kph on the way to work. White shirt, tie, dress shoes... The bike has a 25 kph cut off speed. When I am in shorts I ride like an animal...

I heard my name... I still use 12S because I have a couple of balance chargers on hand but my battery is now 2x6S Li-Ion connected in series. I wanted 12S to reach a certain RPM to prevent back EMF problems I was having. After some testing I think 13 or 14S and a new 48v controller is...

I'm interested in how you get on. For me a tiny light weight battery works for a motor you only need 250-350 Amps peak. I have been toying with the idea if an ultra light weight motor wheel - 1.7 kg - and an 11 Amp peak controller. Just something to get me out of the house, the rest of the ride...

OOOOO! I like that one. Mine has developed a tiny bug and shows 907 peak Amps... I think I would have noticed a burning smell if that was the correct number... The battery being about 2 metres from where I would like to mount a multimeter is a bit of a challenge. Multimeter with Bluetooth...

Yes there is a clause in there for those and for segways and other balance boards. 25 kph top speed for all.

Local news: A drunk 22 year old ran over a 17 year old and killed him. Problem was the 17 year old was walking down the footpath in town at time of death. Footpaths are dangerous places for pedestrians! Drunk driving is illegal. Thousands around the world are killed by drunk drivers monthly. I...

One of the great things about riding a pedelec is that you stop for pedestrians, red lights, the whole caboodle. It doesn't cost you any effort to get on your way again. The most difficult thing is explaining to little old ladies you are not going to run them over...

If I was still living in a flat place I would agree with that. My leisure bike has a hub motor but my commuter has a mid drive to tackle the really steep gradients between my home and everywhere else. There is no way my Mxus XF08 could handle pulling 50+kg trailer loads back from the garden...

https://www.boxcomponents.com/ Came to my attention because they are bringing out an 11-42 8 speed e-bike cassette. Long cage 9 speed rear derailleur to fit. Yes it is MTB oriented but those of us who live in steeper parts of the world can benefit from a wider range. By pure coincidence last...

Personal transport vehicle enters the French road code today, 26th of October. Helmet, high-vis vest, lights on 24/24, 25 kph top speed... Haven't read it all because I don't have one. Fine of 1500€ for not complying and 3000€ if you get caught a second time.

Many of us are happy with the suntour NCX seat post, yes they do work, I was a long time lower back pain sufferer until I got one.

I rummaged around in my computer cable box and found some old series cables which I chopped up. There are more wires than I need but the diameter is about the same.

That is very interesting that the front derailleur reaches far enough out on the TSDZ, it doesn't on the GSM. Easy enough to fix with an extended derailleur mount, I have the bits but am going ahead with rear motor. Gearing will be triple up front for the moment but I am interested in a 46-30...
