For me, its that the second battery is available now and I want to do longer rides. The advantages are that its higher capacity (375whr vs 250whr for the extender) and available. The disadvantages are that its more difficult to carry (pretty much requires a rack) and when the main battery dies, you need to stop and swap it. The extender mounts to a bottle cage and (I'm told) automatically takes over when the main battery dies.What's the consideration between having a second battery vs the range extender? Price, benefit, etc?
This is Réjeanne husband ,yes I did a lot of research on all giant 2020 models on the sport and pro motors before ordering my road e pro 2020 in December 2019.All my research came with the same conclusion that all the models syncdrive +pro 2020 had a Auto mode this year. I received my bike at the end of January and scroll all the modes and auto was under the off mode like it is suppose to be. But we received my wife Revolt e +pro 2020 westerday and tried the same scroll yesterday and this morning and Auto mode is not on her bike. But the dealer here in Tracadie-Sheila N-B Canada ordered a ML by mistake my wife bike is a medium he has it in his store in display all fully charged ,be sure that I am going to be there when they open the store today to see if his ML has the Auto mode.
I just test rode a 2020 Revolt E+ Pro in Ephrata, PA. ( Shout out to Martins Bike shop - outstanding!!!!) The bike was wonderful. It handled like a road bike, despite the wide gavel tires. Very reactive, unlike a Cannondale Synapse Neo SE that I rode last year. Reasonably light weight and very comfortable. With a 1X setup, the shifting was great. The motor worked seamlessly and hardly made a sound - I love this motor! I was ready to buy and take it home until I realized I had done a 9 mile test ride on moderately hilly terrain which included two half mile, 10% climbs and was returning to the shop with 62% battery left. It indicated I had 28 miles left. That's a total of 37 miles! I rode the bike in Auto for the whole ride. The ride extender, available by the end of next week, would have to be used all the time for our group rides in NJ. That takes away a water bottle cage!
To me it seems that Giant went from 500wh to 375 to lower the cost of the bike, but virtually everyone will need the extender adding about $300 back to the bike. I would far rather pay a few hundred more and get decent range and save my bottle cage. If Giant would come out with a 500 or 625 in tube option, I would buy the bike immediately. I think the 375 strategy is a fail.
