December 5, 20178 yr Author Seems a bit point less riding around with 4.4kg dead weight not needed swap the front for a normal hub wheel an if happy with the rear set up sell the old motor wheel. Or alternately with all the rear weight inc battery you may find the front becomes a little light on the steep hills so the extra front ballast may come in handy. Yes, that’s what i thought about keeping the weight on the front. I’m surprised to hear that the FUN motor weighs as much as 4.4kg ? I think putting a new back wheel with motor will be quite straightforward. The only problem could be the disc brake. May have to change to rim brake? Sent from my iPhone using Tapatalk
December 5, 20178 yr The BPM/CST both are about 4.4kg they are 160mm dia hubs. You should have little issue with rear hdb at most you might have to use a180mm rotor and caliper adapter so an extra cost £15-20. Some drop out filing will be needed ( most probably 2 - 4mm deeper) to allow the axle and AR washer tabs to sit in correctly also fit a TA, easier on the disc side.

December 5, 20178 yr I am looking at the possibly of disconnecting the power to the front motor and buying a new back wheel complete with motor and gears. we can supply a rear Bafang SWX02 with disc brake rotor for £150.
December 5, 20178 yr Author we can supply a rear Bafang SWX02 with disc brake rotor for £150. Is that the same motor that i’ve got on the front? What else would i need to buy to make it rear wheel drive? Sent from my iPhone using Tapatalk

Sent from my iPhone using Tapatalk no, that the motor in the Bermuda. We also sell the motor in the hub kits. http://wooshbikes.co.uk/?bermuda It's a 140mm diameter motor. The BPM is a 160mm motor. You don't need to buy anything else. Undo the freewheel from the rear Big Bear wheel, screw it on the new motor wheel, transfer tyre and innertube over to the new wheel, re-install the wheel then connect the 3-pin motor cable to the controller in place of the old motor cable.

No torque bars needed for rear? Can you tell me how much with VAT and delivery or do i need to ring Woosh? Sent from my iPhone using Tapatalk
December 5, 20178 yr No torque bars needed for rear? No. The torque on the SWX02 is about 10% less than on the Big Bear BPM. Can you tell me how much with VAT and delivery or do i need to ring Woosh? that price includes VAT. If you want to proceed, just email support.

Great, i shall proceed with this. One more question. Does this SWX02 turn at the same speed as my BPM. Could i use the two motors together for off-road use. If yes, what else would i need apart from a switch? Sent from my iPhone using Tapatalk
December 6, 20178 yr Does this SWX02 turn at the same speed as my BPM yes. ould i use the two motors together for off-road use. Not at the same time. If yes, what else would i need apart from a switch? You would need to connect the wires to a three pole two throw rocker switch, something like this:
December 6, 20178 yr Author yes. Not at the same time. You would need to connect the wires to a three pole two throw rocker switch, something like this: Great thanks. The switch is no problem, i have one. I would need a motor plug same as one on front. Can you supply? Sent from my iPhone using Tapatalk

Sent from my iPhone using Tapatalk the rear SWX02 motor comes already fitted with its own 3-pin lead and quick disconnect connector like this: http://wooshbikes.co.uk/2017/hubkit/rear-hub-motor.jpg If you want to quickly connect to your alternate motor, I would recommend you use anderson connectors instead of switches. They are far safer in providing high current and isolation than any compact switch.

They are far safer in providing high current and isolation than any compact switch. I don’t think it will be beneficial if i have to get off and change over connectors. If it’s not possible to run both motors at the same time then i may as well make the front BPM motor redundant. Will Woosh be familiar with my requirements when i contact them? It seems the Bermuda had got a 27.5” wheel and Big Bear 26” Sent from my iPhone using Tapatalk

About the Bermuda, you are correct. We sell hub kits and carry a range of motor wheels in 26" rims besides 650B wheels. The SWX02 wheel is also on offer in a complete kit. http://wooshbikes.co.uk/?hubkits#swx02kit

December 6, 20178 yr Author I have got the option of having a new freewheel fitted. Is it a straightforward job to swap my existing one over. Are there any loose bearings in there that i will need to place into the new one? Thanks for info. Sent from my iPhone using Tapatalk

It is a straight forward job. When choosing one, ensure the hole in the centre is big enough to go over the typically larger ebike rear axle.

December 8, 20178 yr Author They all tell me that i cannot use two motors at the same time. I have an idea. I fit a small battery and controller to my front rack. Connect it to my front BPM motor. Fit another throttle, one each side. And use it as a two wheel drive when needed in those muddy off road lanes and fields. Sent from my iPhone using Tapatalk
December 8, 20178 yr As the motors are the same speed with a separate controller and battery you could if you wanted to connect to the same throttle and activate as one. Alternately for permanent two wheel drive connect them both to the same pas.

Alternately for permanent two wheel drive connect them both to the same pas. I’ve been told cannot connect to the same for premanent two wheel drive? Maybe it would cause overheating and damage to the controller or battery? Also, it would not then be road legal as it would be 500W. Is this right? Sent from my iPhone using Tapatalk
December 8, 20178 yr I’ve been told cannot connect to the same for premanent two wheel drive? the motor's 3 phases have to be sync'ed to the position of their magnets. If you have two motors, there is no simple way to lock the position of the magnets on the front motor to the rear motor. That's why you have to use a specialized controller that has two motor cables. http://www.szktdz.com/en/news_show.php?article_id=523 http://www.szktdz.com/upload/image/20170527/20170527084352_29295.jpg
