    The Cyclone 7500 does not have a gear box, so it will spin at insane speeds (compared to the Cyclone 3000 which has a 6:1 reduction). Is it stronger? Maybe not. 120 amps is just 3 times the current of the Cyclone 3000's controller. Without that 6:1 reduction, it may only produce half the torque of the Cyclone 3000.

    This guy has lots of videos of this Cyclone 7500 bike. https://www.youtube.com/watch?v=KemJO_B2FGE

    As for cadence, yes, forget about pedaling along with it. Even the 3000W is pretty much useless for "pedaling along" Mine spins at 350 so I just "pedal along" even though my legs don't do anything.

    Pity, but glad you got it working with a non Cyclone motor.

    So I ordered 2 sets of adapters

    the NINER BIOCENTRIC II EBB ECCENTRIC BOTTOM BRACKET is awesome and with some Hollow alloy Tube and some longer Bolts was easily extended to a 100 mm BB

    but is unfortunately too big for my Bike so returned it.

    the £5.00
    J&L PF30/BB Right/BB386 EVO>BSA Bottom Bracket Conversion Adapter/Convertor

    fits and with some home made spacers work perfectly

    I will add some pics tomorrow

    its £84 or $89

    but caters for thee BSA screw fit which means a 33 mm shaft

    they will need longer bolts and some spacers for for the extra bolt length as these don't appear to come in 100 mm







    SWEET YEA

    Very nice indeed and if it works out okay, it'll open up a host of different bikes for the BBSxx. :)
    Great work!

    Seriously cool info on those BB adapters. Are they plastic or aluminium? I would hope the latter!

    I think I would go the more expensive option (weird that as there is less material there!) - that way gives you more flexibility with separate spacers. The other (Pic2) may need spacers anyway - pity you can't get measurements of that.

    How much $$$ are we talk here?

    Edit: Never mind, found them on ebay. Not extremely cheap then. ;)

ID:	9386 PF30/BB To BSA Bottom Bracket Conversion Adapter / Converter

    As I looked more closely

    there will be several issues

    1. the motor will not be flush to the BB (I knew this from my other bike)

    2. the motor would be too long as i had a 120 mm BB BBSHD

    3. the motor spacing between the axle and the casing might not have enough room

    4. I would need Spacers approx. 2 cm

    so I would need
    Eccentric Bottom Bracket Adapter To PF30

    The first Issue is no one does this in 100 mm BB only 68 mm but that just means sourcing longer bolts


    so now i need to decide which way to go

    Pic 1

    Negative points

    Longer Bolts
    Needs Spacers
    Expensive

    Positive Points

    if fitted at the correct angle will mean the Motor will be further from the frame so less gap on motor side ( but excess is on other side)
    Better chain line
    ​can be angled for frame clearance

    Pic 2


    Negative points

    Longer Bolts
    Needs Spacers Possibly??
    unsure of thee size of built in spacer
    longer delivery

    Positive Points

    spacer there and solid for the motor fitting
    can be angled for frame clearance
    Third of the Price

    as im away for a bit delivery may not be a problem

    You are the first builder I have heard of adapting a PF30 BB to a mid drive, so I will be watching with great interest. Thanks for posting pics to help others who want to do the same thing.
