Sabrina in Velowave email support 5 star

She recommended off- controller and main be replaced instead of battery. She was right! No soldering just two Allen wrenches that came included with package . Thankyou for sending video links also on how to install new controller and main wire.

Off road controller

This is a good purchase for someone looking to increase the top speed of their bike. It took my top speed (I weigh 150lbs) from 20mph to 33mph on flat ground. It did not change how fast it accelerates but does increase overall top speed.

I have a guestion

Once you connect the off road controller can you program it back to on road with the settings?

Hi William,

Thank you for your comment!

Please go “” Advance Setting” - “”Speed Limit“” to limit the speed.

Next Level

I purchased the off road controller and installed it relatively easily. After the install I reset the "Advanced Settings", and it made a world of difference. I've gotten it up to 36mph and I'm 215lbs. It's an awesome bike I'm proud of owning that stands up to the competition in its market.

gain speed

the controller gets me to 30mph if ground is flat or down hill, otherwise about 25mph over all I'm happy it's a lot better then it was. alittle tricky to install but not bad

Randy Vance
Not sure it’s worth 175

Didn’t speed anything up my bad as it said it unlocked 20 mph I had already did that on my own. It was a sucker getting it to fit back in the case. But I learned where everything goes

Dear Randy,

Thank you for your comment. We do apologize for the inconvenience caused to you.
Did you unlock the speed under 'advance mode'? Please email for further assistance. ;)
