Big Sur 26" Ebike

While I enjoy riding the bike, there are several things that could make it better.
1. I have had the chain get stuck twice now between the gears and hub wheel when trying to adjust down to 1st gear. I have taken it in once to the dealer to have it adjusted but it occurred again. The 2nd time it was extremely difficult to get released in that I am considering carrying some type of tool to to grab the chain and provide me a better pulling point. I now try to prevent this by staying far away from 1st gear.
2. An even bigger issue is the lack of adjustment on the torque sensor. I want to be able to adjust the amount of effort I apply for more exercise. To try to extend the range to the maximum, I use level 1 assist and monitor the wattage being used and try to keep it around 100 to 150 and/or the cadence to around 30 or so and/or speed between 10 and 12 mph while peddling. I find the bike too easy to pedal and don’t feel like I get to put in any effort on my part to contribute to extending the range. Today I rode for around 3 hours mostly at this easy rate along a bike route in Houston which is mostly flat although it was a ride along the Buffalo Bayou and White Oak Bayou so did have some up and down movements on the trail. I would coast on the downward trails and coast when I found myself exceeding the above parameters until the return portion when I increased to level 2 and quicker cadence and speed up to around 17mph and ended up using around 70% of the battery.
3. The bike manual is not complete and I believe has at least one error when discussing the screen view on how to adjust between ODO, trip distance, cadence, etc. The manual on page 28 says to hit an i (info) button to change between views but I think it should actually say hit the power button on the display. The display description on page 26 says item 5 is Time Indication. Is this meant to be the elapsed time of the trip, total time on the bike or just a clock. It says there is Bluetooth indicator on the display. What is the Bluetooth indicator for? Do not see any description of it’s use other than it is there. Some really cool app that will capture all kind of great ride statistics and map via a gps phone or other gps device? Don’t bet on it as I have not seen any Android Apps although I have to admit I did not check my iPad for apple apps. Should we expect an app that will work with the bike? The manual does not include a section for how to reset trip info on display.
4. Found the info on how to reset the trip info on the display panel in the frequent questions section. Don’t understand why this was not include in or with the manual. Do not understand why this document is not located alongside the manuals for the bikes on the website. Shouldn’t be so difficult to find.

Item 2 is the biggest issue to me. Need to be able to adjust the level of assist provided for the different assist levels to allow user to put in more effort while riding. Currently it is all or none with the assist levels just allowing a higher rate of speed.

FYI… I use a QuikRStuff bike rack and ramp to move this heavy bike around. Expensive but seems to work quite well for me although there are a couple of pinch points and idiosyncrasies.

My wife and I picked up two of the Big Sur ebikes last week and have been absolutely loving them! We have ridden for at least a couple hours every night after work and the smiles never leave our faces.

We were comparing with the Aventon Aventure 2 and feel like the Big Sur’s are more comfortable, equally powerful, look better (loves the tan sidewall tires) and the standard grips and saddle are much better from AIMA. The larger rear rack allowed us to put two large bags on the back that carry all the gear we need. They’re great bikes on or off road and turn heads everywhere we have been riding.

Only one small issue so far - the front fender has two support bars that attach to the wheel and one of the bolts on my bike worked loose and fell off so now the support bar and fender are flopping around. Have not been able to find any AIMA parts online so hopefully somebody from the company reads this and lets me know how we can get a new bolt!

Be careful changing gears up or down hills this thing almost left me stranded in a canyon after the gear linkage system rolled up like a cartoon.

First time test drove Big Sur. Very nice. Almost identical to Mokwheel except it has a weird ECO feature, have to pass 15mph to get into power mode. I did not see that on Big Sur. Will need to add a neck to bring the handle closer. I also need to know how it handle steep hills and what is the NM?

This bike has given our special needs son his independence back!! (We had the throttle disabled for safety reasons). He is a 6’4” large framed gentle giant who works 5 days a week and lives independently but does not drive. He loves the bike, feels it supports him well and we are so happy with the safety of this bike.

Our only issue is getting enough storage for him to get his groceries home. We have a large back rack and saddle bags but are in need of a front rack to fit the Big Sur 26. Could you please recommend a large front rack for this bike. Thanks!!
