Boosty.ch motor kits

[VSkudarnov]

These are former Bike Elektro Antrieb.

They offer 250-400W geared motor kit http://www.boosty.ch/en/conversatio...age=flypage.tpl&product_id=207&category_id=17.
The motor looks familiar, who is making these?
They use a brushed motor, how reliable are these?
Good side:
Mounting bracket is well-done,
they offer 8T freewheel sprocket so cadence should be easy to match. Typical swiss rip-off price, though

Thanks.

They also state that for additional price, they can do a helical-cut gears to reduce gearbox noise!

Right... 200 euros extra to have helical gears on a 20 euro motor

But I think they do not do it - I am sure they order it from the manufacturer, and it cost much less.

Also, the mounting kit http://www.boosty.ch/en/conversatio...age=flypage.tpl&product_id=229&category_id=17is nice, but it EUR 100 !!! Is there any way to find it elsewhere?

I mean this piece:

I think it is the clamp to 4inch (100mm) drainage pipe, but don't know the exact name for that, and where to look online??
My local household store does not have these - but I will never pay $150 to boosty.ch for just a mount.

I haven't seen anything exactly like those but try a search for "band clamps".

Broken pipe hole repair covers, $13 -$23
3" long, single-bolt clamp diameters shown below. You can replace the bolt with a section of all-thread (with two-nuts each) so as to have threads on both sides of the clamp. There is also a 6"-long two-bolt version (about $20 more). Keplers seat-post clamp is a music-drum stand clamp...

If a flat mounting surface is helpful, an aluminum channel can be bolted to this clamp.
