    Bought it as an accessory.. worked great but then just died on me all of a sudden. Screen just never came back on. Never rode the bike too hard before that either. Disappointed but it did work well.

    This was a replacement for my original monitor, which was stolen. Installation was easy and it hooked up without a problem. Shipping was quick. Ride1up has amazing customer service.

    Very happy. I like having more psa options and the additional info. However, I would have appreciated having this as an option when purchasing the bike at a slightly lower price rather being left with a unit worth nothing. Rather wasteful.

    This really makes it so much easier. I got this installed on the bike, not as an accessory. I really liked that.

    I opted for the LCD display. Yet I still received the standard display plus the LCD display. Seems like a waste of resources. Why not deduct the cost of the standard display and only ship the LCD display? I have not yet used the LCD display. I am still testing the bike with the original display. Therefore, I cannot comment yet on the LCD display.

    I like the LCD but the user manual could be better written. Some instructions are confusing. e.g. page 4 talks about power levels 1-5. says “gear to level 5” but doesn’t say how to do it. Is power level 1-5 the same as assistance level 1-9?? or are they two different things? and how to switch between them?

    I haven’t received it yet as it is backordered but from an on-line review, I believe it will definitely be the way to go since it gives you 9 levels of peddle assist instead of just the 3 with the default display. For me, the 3 levels offer too much peddle assist so having extra lower levels of peddle assist will be helpful.

    Nice upgrade from the stock basic panel. Pedal assist 9 is fast- need to get a new front chain-ring so I can actually pedal instead of pedal-wheeling. Didn’t come with any directions but was a pretty straightforward install. I found a video on youtube that walked me through how to navigate the settings etc.-basic instructions would be nice.

    Get this upgrade. The 9 pedal-assist settings are very handy. I commute on a congested mixed-use rail trail and it is really helpful to just hit the switch to fine tune to assist level when things get crowded or to crank it back up during open stretches. It is also nice to have the speedometer and odometer.

    I feel that if someone is purchasing the upgraded LCD display it should come installed. Installation was easy to do but it seems like a waste to now have an LCD display that will never be used when you could use it on future bikes saving parts and materials which would be better for the environment. Please consider this for future sales.

    In my opinion the LCD is a “must have” upgrade. It allows you to track mileage, speed and most importantly fine-tune the amount of boost you would like according to you needs.

    Definitely worth having so that you can see your speed and miles ridden. Also for riding really slow, like in a crowded campground, the lower assist powers work much better. Power level 3 or 4 is like 1 on the old one. You can just putter along and smell the flowers or turn it up and take off.
