SORRY, THIS KIT IS NO LONGER AVAILABLE
This kit uses the the Magic Pie system from Golden Motor and really the first thing to say about these kits is that, at 1000w. they would immediately make your bike illegal to use on the Queen's Highway! We therefore cannot recommend their use on bikes which will be used on public roads or in any way condone such action!
Now we've got that out of the way, these kits are pretty quick! Each kit is capable of taking you and your bike to way more than 25mph. This will, of course, depend on your bike, your weight, road conditions, terrain etc.
The kit comes with a thumb type throttle incorporating the battery meter, rear full suspension rack along with 48v 12Ah Li-Ion battery pack. The kit also the pedelec (pedal assist) components but note that the pedelec function is almost redundant and you are, in my opinion, better off not bothering to install it!
Please note that this rear wheel kit will only take a threaded, free wheel, cassette so you may have to obtain one of those, dependent upon your existing bike.
Apart from the possible need for a cassette, the kit comes with everything (please see below) you need to convert your bike including full and detailed instructions with easy to follow pictures!! (Took the pictures myself so no strange "lost in translation" Chinese words either!)
Notes: The width required between the rear dropouts to allow the motor wheel to fit is 135mm. The wheel does have an integral fitment for a disc but, since there are so many variations in caliper position we cannot say for certain whether it will fit your bike! Bar diameter for fitment of throttle is standard 22mm.
Please note that because this kit uses a rear mounted battery carrier it has been impossible to design a universal fit as some bikes have lugs on the frame below the seat for mounting the carrier arms, some don't. You will therefore need to be a bit mechanically minded to fit this kit and may need additional fittings such as nuts and bolts over and above those supplied. Also, apart from being totally illegal to use on public roads, this kit is not for the faint hearted and you will have to be absolutely certain that your bike is capable of handling the power provided. AlienOcean take no responsibility whatsoever if you use this kit on your bike and anything happens to you at all regardless of circumstances!!
