No markings visible at all except a warranty seal and no logo or branding :D just ordered a 48v version no stock in Germany till first week of june cost £278.00 this time:oops: thanks for the link will resist the temptation

The comparison is not a fair one the inner tinkerer loves the bbs02 500watt and the extra grunt but the choice of a bbs01 250watt 15amp and this is a tougher, I like the bbs01 when I bought this I never dreamed :eek::eek::eek:this outcome. But as a out of the box option I think for most...

FINISHED AND I MUST SAY I LIKE THIS LTTLE MOTOR A LOT :):rolleyes:

The battery is the biggest part of the bike;) buy cheap buy twice I found out that the hard and expensive way

The 750 watt draws 15 amps how deep are you pockets and how much weight do yo want to add my personal opinion is no cheap Chinese cells get a branded cell Samsung or Sanyo ga cells the pack needs to be around 17 ah at 48v the tsdz2 will not run 52v packs without modification try not...

What version how many watts is the motor and how much range do you need also what terrain is it hilly

Now on ebay

The 350 watt is not worth it to little gain [ I have one in the trike ]if you want a 36 v system the 500watt bbs02 which is set to 25 amps as standard is the one, its also available in 48v if you hunt around for it :D or stay legal at 250 watt version more power = more battery cost cheap...

The alfine runs well with the gearing of 18 on the rear and the standard as supplied chainring on the front ,the 15 ah is ok , but do not try the 52 tooth on the front the top speed is higher but you risk burn out as an aside the tsdz2 is ok up to mid 20s mph as well

You need to be careful not all versions of the bbso1b will go above 15 amps it a firmware thing and the luck of which batch you get , the standard 15 amp will do over 20 mph with ease on the flat

It is tiny motor also has no logo or stickers on it the 750watt is the same size package:rolleyes: I wish I had gone for that :eek: but wanted a legal version again

Still waiting for the battery box to arrive [ do not laugh at the bungie tie round the battery ]but a longer ride showed the gearing to be to fast ,so on with a 36 tooth bling ring the little black cog on the rear axle is the diff now pulls 750watts peak runs 250- 300watts at 15.5 mph thinking...

Had a longer test ride today:) now I understand how to use the pas levels to match gears and pedal effort required cannot get away with ghost pedal trick any more;) A much happier more relaxed ride found I spent more time enjoying the countryside rather than if I had used the bbs02 that is...

The battery is the most important part of the set up mine came from jimmy at insat it cost £450.00 the cells are Sanyo ga [Panasonic] you will not get a cheap battery to do any sort of long range or last very long [ think turbo car cheap petrol ] you need a quality cell A standard 250watt...

I have just sold my bike with the em3, the motor is great but with high current the battery takes some stick had 21ah with ga cells which copes ok but a no name cell would fry I think 48 v is the way to go now

The test ride completed my first impressions are its not going to set the world on fire.:confused: But in the words of a tv add it does exactly what it says on the tin and it does it very well , as a legal 250 watt 36v motor with a 15.5 mph cut off and at the price good value for the money...

Strapped the battery on with a couple of ties fitted both the rear discs and off round the field for a test ride ;) great up to about 25 mph :D:D:D:D. The 3 speed hub gears provide enough low down grunt , surprised how far cable operated discs have come in a few years the 203 mm on the front...

The way round this is to drill an extra hole in the down tube and fit a product called a rivnut [ a captive bolt once tightened ] check you tube for a vid this is a quick and more important a tidy way round the problem sorry about the music watch with the sound down:rolleyes:

I built this one comfort and speed 35mph:D plus To get what you want will mean build it, or modify a shop bike

so ugly I had to save it as it , has a rear diff so the cornering problems are solved .It now has bbs o1 and the tyres just keep getting bigger twin wheel spins:eek::oops::rolleyes:
