I have been viewing your various 20&#8243; 48v\/52v front hub motor <a href=\"https:\/\/www.leafbike.com\/products\/diy-bike-conversion-kit\/\" rel=\"noopener\" target=\"_blank\">diy bike conversion kits<\/a> and I have a couple of questions.<\/p>\n<p>1) Is there a way to install a disc brake rotor somehow next to the <a href=\"https:\/\/www.leafbike.com\/products\/e-bike-hub-motor\/\" rel=\"noopener\" target=\"_blank\">hub motor<\/a> and still function properly? If so, can you tell me maximum rotor size allowed for these kits?<\/p>\n<p>2) What type of battery would you recommend for a 48v\/52v front hub motor kit like this?<\/p>\n<p>Thank you very much\u00a0for your time and assistance regarding this matter.\u00a0<\/p>\n<p>A: 1.) Can install a disk on this 20 inch 1000w or 1500w front hub motor&#8230; but the front dropout should be 105mm or 110mm..<br \/>\n\u00a0 \u00a0 Standard front dropout is about 100mm..<\/p>\n<p>So if the dropout can&#8217;t be larger, can&#8217;t use disk on front motor.<\/p>\n<p>2.) We recommend 52v 20ah lithium battery.<br \/>\nhttps:\/\/www.leafbike.com\/products\/lithium-battery\/52v-20ah-1500w-electric-bike-battery-triangle-battery-1225.html<\/p>\n<p>Q: Thank you very much for\u00a0your quick response. Do you know what the maximum disc brake rotor size I would be allowed to install next to motor? Thank you again.<\/p>\n<p>A: We installed max 160mm<\/p>\n<p>Below picture.\u00a0<br \/>\nThe dia. of two holes for disk is 44m&#8230;<br \/>\nIf your 180mm 203mm, \u00a0aslo 44mm&#8230; You can install 180mm, 203mm disk<\/p>\n<p>Q:<br \/>\nI forgot to ask you one last thing before making a final decision on a front hub motor kit. I know you said you are not able to ship the recommended 52v 20ah battery to Japan, but can you recommend a charger to go with this type of battery? Thank you again for all of your help and assistance.\u00a0<\/p>\n<p>I just noticed the charger that comes with the 52v 20ah li battery, so I can look for battery\/charger here in Japan. But, do you have in stock just the frame bag for holding this type of battery?<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Q: Hello!
