Customer Reviews

Like better than Cateye Micro wireless for eBike
I was using a Cateye Microwireless on my 36 V eBike and the unit would stop displaying speed/miles whenever I turned the eBike light on. The BC1606L, as it is a wired unit, solved the problem and now I can display speed/miles with the eBike light on. FYI, install was straightforward but I would suggest getting additional nylon cable ties to secure the sensor to display wire as you can route it along existing cables and just use the ties to hold it in place. If your bike frame is colored [mine is red] you can get colored cable ties [www.mcmaster.com] which will make the installation look better. The unit comes with a cadence sensor but I did not install mine and cannot comment on this function.
With use I have found additional advantages over the Cateye. The display digits are larger than the Cateye and are easier to read. Resetting the trip odometer and resetting other functions is easier than the Cateye. The night light is bright and makes the display readily visible at night.
Bottom line. The large digits in the display are nice and eliminating the interference on an eBike for night riding worked fine.

Worked Great For Me
I'm a casual mountain biker and this computer works great for me. It seems very accurate, was easy to install, it's easy to read while riding, and it has more than enough functions for my needs.

Good Value
The only thing I have to compare this to is a cheapy $8 one I had from Kmart many years ago. This Sigma 1606L has many more features including cadence which I use often. The data it collects per trip ( average speed, average cadence, max speed, trip time, trip distance) is saved so I can transfer it to a spreadsheet to track how I'm doing. It's easy to remove from it's base using a bayonet style attachment, which I have placed on the handlebar stem. I was not impressed when I saw how the parts mount to the bike, thin rubber O-rings loop around sensor and fork, or baseplate and stem to stay in place, but after 1000 miles on streets and bike paths everything has held together. It always shows current speed plus any other selected single feature, like cadence or time.
Why only 3 stars?
1) Lacks a scan feature, so I must push a button repeatedly to get to view the function I want. An auto scan feature would allow me to keep my hands on the grips where they belong.
2) The wiring is somewhat flimsy. Small gauge wire is subject to breaking if put under any stress.
3) Speed readout shows only the closest half mile interval, doesn't show tenths. For example, it reads either 12.0 MPH or 12.5 MPH missing 12.1, 12.2,etc.

I am actually very happy with this nicely designed and low cost unit. Mine came with a second mounting for a second bike, data for which it tracks separately. After 8 months of use over many miles, it has served me well.
