View source for Throttle Lock

<onlyinclude>
;Goals
: Generally, a throttle lock is a cheap way to get a basic cruise control mechanism.
: Electric motorcycles never stall and have a broad torque curve, so throttle locks are very effective despite their simplicity.
: A Zero with a cruise control will speed up and slow down to maintain an overall constant power/torque output, which makes range and power consumption much more predictable.
: 5% range gain can be had just from removing wrist adjustments from the throttle.
: Holding a throttle steady is a source of fatigue, so a lock helps minimize that.

;Hazards
: Any traction loss with an electric motor while using a throttle lock is dangerous.
:: The rear wheel could spin up rapidly, faster than one's reaction time.
:: This wastes precious seconds when the bike could lose stability and go down, when the throttle should be immediately eased off and balance recentered.
: For this reason, using a throttle lock should be limited to highway stretches with good visibility and no traction risks.
: Make sure, otherwise, that you can release the throttle lock very quickly and easily to avoid an emergency.

;Tested Options
* [[user:BrianTRice|Brian Rice]] found and installed an [http://www.atlasthrottlelock.com/ Atlas throttle lock] which seems to suit the Zero well, particularly because it avoids taking up valuable handgrip space and has a generic fitment. The Magura throttle's space for the Atlas to fit into is extremely narrow, though.
*: Atlas nicely posted a [http://www.atlasthrottlelock.com/pages/throttle-lock-comparison-chart comparison chart] illustrating how different throttle lock mechanism approaches have tradeoffs.
*: '''NOTE:''' The original version (before top and bottom mounts were distinguished) was thinner and easier to fit.
*: [https://www.facebook.com/groups/zmcowners/permalink/1708192532583281/ Some have reported] using a fine amount of milling to fit the Magura throttle on 2013-2014 models, and even for later model years.
* [http://www.2wheelride.com/throttle_pro.html Go Cruise throttle lock] is generic and easy to use, but does take up space on the inside of the throttle grip, which can make the throttle and mode switches harder to use.
* [http://www.kaoko.com/ Kaoko throttle locks] operate as bar ends with a dial and are good if the bike fit is confirmed, which Zero does not have.
