"It even has a bottle opener..." I wonder if the Strömer has a cork screw? Nothing wrong with a good bash plate, especially one that sits slightly below the chainring. The Husky one looks just right to my eyes in execution and material selection. I have to agree with the barber that alloy bash...

I realize that the Levo has a Brose engine but this still applies. Bosch's War on Self Repair · It's Code Red If you are brand loyal and your idea of repair is to take it to a certified mechanic, hopefully under warranty, there is no other option. eBikes can be super simple or complex with the...

"Also i don't see why it would be neccesary to charge them at 7a?" Only to get a quick refill during the course of the day as necessary? I have a 500wh battery that I can ride for up to 4hrs. on and quite frankly I am worn out a bit before the battery dies. There are some rides though that...

As I understand it maximum charge rate is based on the individual cells capacity and p'ing them doesn't change that and in fact is necessary for them to even be charged at a full 7A as per this snippet from an engineer at a well known German battery supplier regarding a 21700 cell battery we...

Given this: KTM industries launches electric bicycle brand - electrive.com Ms. Puello is my kind of gal. She got the eMtb going at Accell (Haibike) and then must have seen their long range plans, that ended up with their latest offering, and left to continue her vision which the above...

There's an old saying: "Locks only keep honest people honest" That said for errands and a quick run into a shop I like a small round cable lock that I keep slung over my shoulder and rides against my bag that I use for errands. Just enough for around the top tube and the bike rack pipe and easy...

"Well according to the TQ site there will also be a 45 km/h s-pedelec version, a very developing market." After reading the motor specs and seeing the lighting package that is what I thought it would be good for. Slap on a plate holder, a rear view mirror and some slicks and you'd have a dandy...

Me too. To my knowledge this is the highest mAh battery available in the 21700 format: https://www.bmz-group.com/dokumente/BMZ-21700-50EL_36629.pdf As it is not a good idea to charge a battery cell beyond is rated capacity, especially 3A, I don't think that is the one in use. They are tight with...

Granted I do ride a hard tail but where I live rocks and roots come in all shapes and sizes.

"Hm, i don't get it, but maybe i missunderstood something. If i pedal and my pedal will hit an oncoming root, i have to stop pedaling (or back pedal a bit). If i brake or not doesn't matter, that pedal will hit the root if i don't stop pedaling. Braking would just change my speed but the pedal...

Is the reason you are all using shorter cranks because you get pedal strikes if you stop pedaling enough to properly time your cranks like you have for years on your dino mtb? Because the assist shuts down is it harder to work your way through tech as it takes whatever amount of crank movement...

Charge rate is determined by the maximum charge rate of the individual cells. The LG 21700 is rated for 7A so you could charge a 15ah battery 50% in one hour and 85% if you take a longer break by 45 minutes or so. Depends on how many V your motor is how many watt hours if will be.

Still raises the issue of suspension performance with the extra weight aboard as compared to stock. Not really an issue if you choose to ride with the extender battery on all the time you can just re-adjust the suspension to suit. But switching back and forth, while doable, would be kind of a...

You are right Doom. It is a 10s, it's Saturday and weed is legal here is my excuse.

That is the same amount of batteries as the 10s4p example above in a different configuration. Doing the math 41.4v x 15A = 621w peak which lines up with what I have seen as an accurate # and is a 14.4ah/518.4wh. No way looking at the pic that you could stuff 21700 cells in there, the extra...

Hey Kiwi, As far as I can figure never having had one opened up the Levo standard battery is a 12s/3p. 12 cells long by 3 of those high. 12s x 3600mAh (usually arrributed to 18650 cells of high caliber) = 4.32ah 12s x 3p = 12.96ah (36 cells total) 12.96ah x 36v = 466.56wh Close enough for...

Considering the fact that electric cars take between 2,500-5,000 cells per car manufacturing and supply line is in place, contracts for them must be in the millions for some accounts. However a 48v 15ah 21700 battery only takes 39. So even if you are making a lot of batteries it doesn't add up...

Life's changing and so are it's lessons.

I am not at Eurobike but have been following the progression of battery technology for a number of years. My first eBike in 2001 had a SLA one which was a really poor performer but peaked my interest about eBikes enough so that I have kept my eye on them. Batteries are the heart of any eBike and...

Back in the day when I rode MX on a 125 2smoke there was only one way to ride it and the common term was "keeping it on the pipe". This meant to keep the rev's as high as possible and shift, no clutch, around to keep it at peak rpm's. The 125's of the era, dare I say the late 60's, didn't put...
