    Going Where I've Never Gone: Need basic background info on "single speed" and related components

    Hi All, I'm not a novice and I'm not an expert on what I'm asking about - obviously! I'm ignorant but not stupid! So you get where I'm coming from, etc, a little bit of background: WAY back in, oh, late 2016... I think, I got hit by a car while bicycling and kept injuring myself (and making it...

    Amsterdam has Beer Bikes - who knew?!

    ...I was reading a BBC article on the web and this caught my eye: Looks like it sports 12 seated pedalers and at least three seated freeloaders, though the driver may not be so much free loading as just freed from having to pedal! If I were managing the design, construction, and operation of...

    "48V" DC - DC converter cut-off voltage question

    I'm planning to add a DC-DC converter to at least one if not both my TSDZ2 48v bikes so that I can add robust 12v lighting for night riding - including lighting for my trailer - and after spending hours looking at options, it looks like I've got really two options that financially make sense...

    What headset?! New Frame, incomplete headset data - HELP!

    Hello Bike Geniuses! I've got a new frame on the way and am attempting to conduct my very first frame-up build. The frame is a Marin Bikes Stinson Euro, never sold in the USA, and discontinued years ago. But a seller bought out their remaining stock of new frames they kept for warrantee...

    Marin San Rafael Euro frame-up TSDZ2 powered build

    Hello everyone, [EDIT: When the frame arrived, it was discovered to be for 26" wheels, NOT the 700C I'd ordered. They didn't have the Stinson Euro model in 700C, so I had to take the nearly identical San Rafael model instead - in a bluish-gray instead of silver. I'm leaving this now wrong data...

    Where to buy Reention DS5 (and?!) mounting bracket?

    Hi All, I bought this battery: https://em3ev.com/shop/preditor-l-47v-8-4ah-11-8ah-frame-battery/ I asked the vendor about another mounting bracket (so I can run one battery on two bikes) but they seem to have ignored the request. So, I went to the Reention site and I think this is the case...

    2nd Bike w TSDZ2 assistance, this time to help with injury

    Hi All, I've had a very successful e-bike whose build thread is here: https://endless-sphere.com/forums/viewtopic.php?f=3&t=88943 Fun as it has been, it hasn't been fun when I've unfortunately twisted my left knee. Things were getting better (it was healing nicely), but as you can read in...

    A 1982 Raleigh 10 speed with TSDZ2 mid-drive

    (title was supposed to read:) A 1982 Raleigh 10 speed pupa metamorphizes and emerges from its chrysalis as a modern E-Bike! In the last week of May, the decision was made to take this old bike and transform it from a relic of the past into a viable part of modern city transportation. It was...

    Making a Battery Pack using NCR18650

    Hi All, In reading up about battery issues, I've decided to skip buying a pack from some far away land that may or may not be what I think I'm buying and which will, either way, cost me a lot of money to ship. ...I'm very handy, so why the heck not?! Shipping only a few cells at a time is any...

    Bicycle Wheel & Gear Spreadsheet / Calculator

    Hi everyone, I created a Microsoft spreadsheet to help me determine how I was going to handle the upgrades to my bike's gearing that are compelled to occur due to my eminent installation of a TSDZ2 Pedal Assist System from Tongsheng. MY issue was that my bike is losing the 52T chainring and I...

    Help with gearing issues on E-Bike conversion

    Hello All, I've got a 48V, 500W Tongsheng TSDZ2 on the way and am preparing for the conversion. One issue that's come to mind is the gearing. I am using this bike for primary transportation and love the gearing now, though it has a lot of overlap in the gears - generally a good thing, but it...

    The New Tongsheng TSDZ3 - anyone have experience?

    Hi All, About a year ago, someone started a new thread here on the TSDZ2 and it's a fascinating thread with some 375+ comments. I dare say, in my somewhat limited exposure to it, that THIS GROUP has created what one might call "the community of TSDZ2 owners", worldwide. I read it all, I'm...
