January 3, 20242 yr Author Email Andy at wooshbikes.co.uk. i am pretty sure he can arrange something for you. I don't need this motor... but I really want it... what should I do? Decisions, decisions, decisions... Is it possible to reserve one motor for me till you check power? It would be very disappointing to find out controller was restricted to 5A lol
January 3, 20242 yr 720W mid drive would make for exciting 20" wheeler riding, if my experience of 36V X 18A (out of a possible 20A) = 648W (up to a possible 720W at 20A) is anything to go by on my Dahon folder, and I sincerely hope someone does such a conversion; reports back. But not on a 20" wheeled folder because it'd probably snap, which would be even more likely at 20A and 960W. Mind you, my bike hasn't snapped (yet) so maybe not? Even more exciting on 16" wheels, something like a Presto SL. No disc brakes, unfortunately. Hub gears on the Presto Lite would die a swift death with that much power, I think.

January 4, 20242 yr Aaaarrggghhh [mention=6303]Woosh[/mention] - you've deleted your post about a HEX file! That and the configurator will turn up on the net sometime, as they have for the TSDZ2, and at that point, I have no doubt this apparently legal 720W/960W motor will be of great interest to torque sensored powerful motor obsessed cyclists throughout the UK - the Bosch ebike market. I'd expect this larger motor to be more robust, more suitable for heavier cargo/trailer hauling than the TSDZ2. Edited January 4, 20242 yr by guerney

January 19, 20242 yr Will the paper gasket be leaky, causing rain anxiety? Everything inside seams to be nicely sealed, so it should be fine unless you are planning on leaving motor soaking in bucket of water overnight. But if concerned it is an easy fix. I am more concerned about cables sticking out of bottom of the motor without any protection. Disappointing.
January 19, 20242 yr I used cable tidy webbing, as cables exit the bbs01b the same way. Adds a little impact protection. Haven't experienced any problems. Cable sheathing is pretty tough, the webbing is probably unnecessary. Having had my motor completely submerged for 13 seconds after a storm left a pond in the road, I'd be inclined to cover most of the paper gasket with heat and shrink resistant silicone sealant, leaving some oncovered underneath to allow exit of expanding hot air and entry of contracting cold air, as the motor heats and cools - did that with my bbs01b, and it has a rubber gasket not paper. Too watertight would be too airtight, causing problems like the controller being blown clean off by hot air, severing a foot? Unlikely. Edited January 19, 20242 yr by guerney
January 19, 20242 yr I used cable tidy webbing, as cables exit the bbs01b the same way. Adds a little impact resistance. Haven't experienced any problems. You use bike to commute mainly. TSDZ8 is marketed for mtb, so you can expect strong impact (rocks, roots, logs etc) Too watertight would be too airtight, causing problems like the controller being blown clean off by hot air, severing a foot? Unlikely. Controller is completely sealed as far as I understand. They will probably sell it with part of the housing.
January 19, 20242 yr You use bike to commute mainly. TSDZ8 is marketed for mtb, so you can expect strong impact (rocks, roots, logs etc) Perhaps some company will start offering bashguards sometime, like the ones for the BBSHD? After months of speculation about all sorts of stuff too numerous and weird to mention on the To7OrNotTo7 "What was the question?" thread, I'm looking forward to reading a thread about your new motor and bike build, despite my not actually wanting to ever buy a torque sensored mid-drive - my interest has appeared by very gradual osmosis through multitudinous exposures to posts about this motor over many long months of postings by various entities. I really should hire an exorcist to rid myself of this interest. There will be pea soup. Edited January 19, 20242 yr by guerney
January 19, 20242 yr Would like but would need a new bike to fit it too, already have 3 and can only ride 1 at a time.. this is the sort of problem i can live with
February 22, 20242 yr Power to you Woosh, a bit like deja vu again really, jerry has been onto this for years, rule only says 250watts continuous and sticker to say so. No mention of max output in rules and we now accept input watts not output. Bosch cleverly claim more torque in newton metres every upgrade whilst maintaining 250w sticker, no-one cares. Speed limit is their clever bit, ebay full on dongles to bypass but their hands are clean, like pontious pilate. Ebikegate might be coming, watch the Bosch execs run ! It's possible to do this in firmware but I don't think it is necessary. You pedal normally with a ts kit. If you want to respect the spirit of the law, you also pedal when climbing a hill, the throttle makes possible to pedal as much as you like. That’s interesting, do they let you change high and low voltage cutouts ? As I’m sure you know tsz2 you had to reflash firmware, either theirs or osf before you could run 52v battery, it would be nice if they let us have access to these at last as well as current values for levels etc. Also, my biggest gripe with Tongy orig firmware was the delay on hitting throttle, does z8 fix this with orig firmware?. Throttle overides pas immediately like with osf ? No power at all going up steep hills sucks.I learnt to hit throttle at the bottom of hills, regulate as needed to climb. Hitting max torque sensitive power fails badly, spin or wheelie in the loose uphill off camber stuff. Bafang with osf so much better. Momentary 25amps at 52v would be nice for steep hills . Not continuous, obviously, that would be illegal. Rules are Dutch, for flatlands, in Wales or even Chingford, speed downhill is not regulated by watts or newton metres but gravity. We also have uphill, mumbo is good we can agree that laws are not perfect, but there are inexpensive solutions My wife had to pay £75 fine through no fault of her own. The car in front stopped suddenly, just for about 5 seconds. This happened at the Green Man roundabout in Leytonstone. She was trapped in the yellow box behind his car for 5 seconds. I do hope they (or you) told her the crime. Junction box rules are simple, enter only when clear to exit. Car in front breaking down or falling asleep is exactly why. I’d nuke em. London often at a standstill cos of silly t*rts blocking the junctions. £75 way too cheap for the livelihoods at stake. I got fined more for very minor speeding, hurting or holding up no-one. Glad to hear they’re finally onto it. Of course the Green Man roundabout worked well before they put lights there but that’s another story. Now the junction box is everything, maybe time for bigger roundabout ?

February 22, 20242 yr 52v battery is not legal. It has to be 48v maximum. House of parliament law or your opinion ? Not in any legislation I’ve seen, certainly not EU law If true, you might note 48v battery fully or even half charged breaks your rule please elucidate facts not utter bs !
February 22, 20242 yr House of parliament law or your opinion ? Not in any legislation I’ve seen, certainly not EU law If true, you might note 48v battery fully or even half charged breaks your rule please elucidate facts not utter bs ! It's written in EN15194!
March 3, 20242 yr Didn't you buy one of those? What's your conversion like to ride? Still in the box waiting for nicer weather.
March 3, 20242 yr One would expect the EN15194 to be 48v nominal and not max as the max figure is stupid one that makes no sense , who builds and uses 11s ?

Perhaps leaving out the term "nominal" when mentioning voltages is a convention used by writers of standards, and one mere mortals aren't made aware of? Edited March 3, 20242 yr by guerney
March 5, 20242 yr Still in the box waiting for nicer weather. I wish you'd get on with it! There's been so much speculation on that horrendously contentious To7OrNotTo7WhatWasTheQuestion? thread, despite myself I'm curious about the TSDZ8, and I don't even want a torque sensored bike. Cold weather be damned, be the first to review! Or keep it refrigerated, like all cheeses it'll go off past it's use by date trapped in a box, lonely in deepest inky dark.

March 17, 20242 yr Thanks heaps for that Az, best emotor review I’ve ever seen, concise words and dyno readings without some smug git filming himself for a video in the web. 52v out of the box woo hoo 24 amps from controller, safe. So nearly the 25 my 02 gets happily, I’d possibly not notice. 73% effeciency on his “ dyno” interesting too, I’d like to see 02 and HD under same test. I “think “my HD is better but may have to rig up similar kit to find out. As and when I can program one of these (Dan Nillson’s OSF .?) myself, I’m in We’re all different but from this I’d have level one similar to first firmware, SFA assistance till you press hard, sounds ideal for shared paths etc, flick it up for road work, add some throttle for hills He doesn’t mention but it would be brilliant if throttle immediately overides pas without the delay of tsz2 or jerkiness of Bafang. Both fixable with OSF , maybe this won’t need to be ? Legal sticker as per thread title too, what’s not to like ?
