It&#8217;s top speed, however, is a joke at around 20mph, so I do not engage the electric motor and let it run&#8230; instead I use a pulse and peddle technique (kinda like pulse and glide to you hypermilers out there). Its simple enough. At around 15mph I punch it to 20mph. \u00a0Peddle till its back to 15 and then punch again. \u00a0You get way more life out of the battery this way.<\/p>\n<p>Anyway, the jist of all this is you can keep a pretty stable speed even with a bit of a climb. \u00a0In these two charts from the iphone app\u00a0<a href=\"http:\/\/feeds.feedburner.com\/~r\/RecentlyAddedIphoneApplications-PinchMedia\/~3\/380771686\/viewSoftware\" target=\"_blank\">TrackThing<\/a>, we can see basically that.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"size-medium wp-image-316\" title=\"picture-078\" src=\"http:\/\/perivision.wordpress.com\/files\/2008\/09\/picture-078.png?w=200\" alt=\"\" width=\"224\" height=\"336\" \/> <img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-315\" title=\"picture-067\" src=\"http:\/\/perivision.wordpress.com\/files\/2008\/09\/picture-067.png\" alt=\"\" width=\"224\" height=\"336\" \/><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-317 alignright\" style=\"margin-left: 3px; margin-right: 3px;\" title=\"img_0033\" src=\"http:\/\/perivision.wordpress.com\/files\/2008\/09\/img_0033.png\" alt=\"\" width=\"224\" height=\"336\" \/><\/p>\n<p>Now the only problem with this, and an issue I&#8217;ve had with other tests, is the occational spike. According to one graph, at one point I was doing 48 mph! And, why are the altitudes different? \u00a0Went from home, to the market and back home. \u00a0Same path. Clearly\u00a0erroneous\u00a0spikes. So what is causing these spikes?<\/p>\n<p>Most likely, its the accuacy of the GPS slipping in and out. A useful app for understanding this is InstaMapper GPS Tracker. When you first turn it on, it uses the cell antenna to locate you, then slowly brings the GPS in as the system finds satilites. \u00a0The more satilite it can fine, the more accurate the readings. \u00a0So the question is; how can we inprove the GPS during our bike rides?<\/p>\n<p>Well.. we will find out soon enough, because I&#8217;m going to do a quick ride friday and try a few things. \u00a0Check back then kiddies. \ud83d\ude42<\/p>\n<div class=\"SPOSTARBUST-Related-Posts\"><H3>Related Posts<\/H3><ul class=\"entry-meta\"><li class=\"SPOSTARBUST-Related-Post\"><a title=\"Why my Tesla M3 feels like my first iPhone and my M3day plus 30.\" href=\"https:\/\/www.perivision.net\/wordpress\/2018\/05\/why-my-tesla-m3-feels-like-my-first-iphone-and-my-m3day-plus-30\/\" rel=\"bookmark\">Why my Tesla M3 feels like my first iPhone and my M3day plus 30.<\/a><\/li>\n<li class=\"SPOSTARBUST-Related-Post\"><a title=\"The Bidding For An iPhone 6 Prototype On eBay Is Up To $94,000\" href=\"https:\/\/www.perivision.net\/wordpress\/2014\/10\/the-bidding-for-an-iphone-6-prototype-on-ebay-is-up-to-94000\/\" rel=\"bookmark\">The Bidding For An iPhone 6 Prototype On eBay Is Up To $94,000<\/a><\/li>\n<li class=\"SPOSTARBUST-Related-Post\"><a title=\"Apple patent application reinvents remote control for the smartphone age\" href=\"https:\/\/www.perivision.net\/wordpress\/2014\/10\/apple-patent-application-reinvents-remote-control-for-the-smartphone-age\/\" rel=\"bookmark\">Apple patent application reinvents remote control for the smartphone age<\/a><\/li>\n<li class=\"SPOSTARBUST-Related-Post\"><a title=\"iOS 8.0.1 May Have A Link To Apple Maps Fail From 2012\" href=\"https:\/\/www.perivision.net\/wordpress\/2014\/09\/ios-8-0-1-may-have-a-link-to-apple-maps-fail-from-2012\/\" rel=\"bookmark\">iOS 8.0.1 May Have A Link To Apple Maps Fail From 2012<\/a><\/li>\n<li class=\"SPOSTARBUST-Related-Post\"><a title=\"Where to? updated and on sale.\" href=\"https:\/\/www.perivision.net\/wordpress\/2014\/09\/where-to-updated-and-on-sale\/\" rel=\"bookmark\">Where to? updated and on sale.<\/a><\/li>\n<\/ul><\/div>","protected":false},"excerpt":{"rendered":"<p>The last week has been insanely busy, so I have not even had time for a quick 10 mile ride in the hills. \u00a0I did however take my ebike to get lunch and did a recording just for fun.
