Well my bike is a Gaint "comfort (aka hybrid with a purty name) bike. i like it so it isnt going anywhere, and i do update it as things catch my eye. Basically i was always happy with the slight vibration, good range good power. Now alas my trusty stead needs a new heart. The battery pack is NiMh which is no longer produced. The original range was 36 miles. In reality my baseline was 5-6 miles in full electric around town, and now it is down to 2 miles. Yes i was (and still am) perfectfully happy with the system.
The new system has a smoother motor, more power, lighter battery (7lbs vs 14). I was forced into the Ni batteries because the Li at the time was way above my budget. I am on a disability income so money is always tight but this wont break me. The downside is 1500.00 for the new system, the PL350. The 250 can be had for 1000 but in my gut that feels too weak for me. At least i can upgrade my lights when i pull the trigger on this.
